	config.guess: x86_64-pc-solaris2.11 is not properly recognized
	config.guess guesses Solaris 11 to run on a 32-bit platform
	despite Solaris 11 no longer supporting any 32-bit platform.

	See the following code at lines 434 to 445:

	| SUN_ARCH=i386
	| # If there is a compiler, see if it is configured for 64-bit objects.
	| # Note that the Sun cc does not turn __LP64__ into 1 like gcc does.
	| # This test works for both compilers.
	| if test "$CC_FOR_BUILD" != no_compiler_found; then
	|     if (echo '#ifdef __amd64'; echo IS_64BIT_ARCH; echo '#endif') | \
	|         (CCOPTS="" $CC_FOR_BUILD -E - 2>/dev/null) | \
	|         grep IS_64BIT_ARCH >/dev/null
	|     then
	|         SUN_ARCH=x86_64
	|     fi
	| fi

	If "cc" is installed, i.e. the Oracle Studio compiler, this one is
	chosen for $CC_FOR_BUILD.  This compiler, the gcc provided by Oracle
	and also gcc bootstrapped from sources on that platform with a default
	configuration will by default generate 32-bit binaries -- even on
	a 64-bit platform.  And __amd64 will not be defined for compilations
	targeting a 32-bit platform.  This is different from the corresponding
	behaviour on GNU/Linux systems where the local platform is targeted by
	default.

	Thus, as long as you do not add "-m64" or if you have a custom-built
	gcc which defaults to 64 bit, you will get 32-bit binaries on Solaris
	despite living on a 64-bit platform.

	* config.guess (i86pc:SunOS:5.*:* || i86xen:SunOS:5.*:*): Adapt the
	test by adding the "-m64" flag.  This will work properly for Solaris
	10 as well (the last Solaris release that supported x86 32-bit
	platforms).

	2021-08-14  Nick Bowler  <nbowler@draconx.ca>

	config.sub: work around command assignment bug in some shells
	When combining variable assignments with a shell command, some older
	shells (notably heirloom-sh and presumably also Solaris 10 /bin/sh)
	have a bug which causes the assignment to alter the current execution
	environment whenever the command is a shell built-in.  For example:

	  % dash -c 'x=good; x=bad echo >/dev/null; echo $x'
	  good

	  % jsh -c 'x=good; x=bad echo >/dev/null; echo $x'
	  bad

	The config.sub script contains a few commands of the form:

	  IFS=- read ...

	which triggers this bug, causing the IFS assignment to persist for the
	remainder of the script.  This can cause misbehaviour in certain cases,
	for example:

	  % jsh config.sub i386-linux-gnu
	  config.sub: test: unknown operator gnu

	  % jsh config.sub i386-gnu/linux
	  sed: can't read s|gnu/linux|gnu|: No such file or directory
	  Invalid configuration `i386-gnu/linux': OS `' not recognized

	* config.sub: Save and restore IFS explicitly to avoid shell bugs.
	* doc/config.sub.1: Regenerate.

	config.sub: normalize the quoting in the `echo FOO | sed ...`
	Some cases quote the argument to echo and some do not.  At runtime
	it probably does not matter because the substituted values will never
	contain whitespace, but quoting them all would make shellcheck more
	useful.

	* config.sub: Consistently quote the argument of echo.

	Remove automatic patch generators
	These tools have served their purposes and need not be kept outside of
	the repository history any longer.  This patch as a diff also collects
	the contents of the various tools in one convenient place.

	* patch-1.gawk: Remove.
	* patch-3.gawk: Likewise.
	* patch-6.gawk: Likewise.

	2021-05-26  Jacob Bachmeyer  <jcb@gnu.org>

	config.guess: manual fixups after previous automatic patch
	The tool could not handle command substitutions that span lines, but
	fortunately there were only two such substitutions in the script.

	The test for which universe is active on Pyramid is rewritten into a
	case block because it was the only use of a command substitution as an
	argument to the test command, which would require quoting.

	* config.guess: Rewrite "if" for Pyramid systems to "case".

	2021-05-26  Jacob Bachmeyer  <jcb@gnu.org>

	config.guess: replace POSIX $( ) with classic ` ` throughout
	The previous replacement of backticks with POSIX command substitutions
	was ill-considered and illogical: this script recognizes many archaic
	machine types that probably never had POSIX shells, therefore it needs
	to be able to run successfully under pre-POSIX shells.

	This patch was generated using the included GNU Awk program.

	* config.guess: Revert POSIX command substitutions to classic form.
	* patch-6.gawk: Store the tool that produced the automated patch.

	2021-05-26  Jacob Bachmeyer  <jcb@gnu.org>

	config.guess: manual fixup after previous automated patches
	This patch provides the special handling for the GNU system.  As these
	were two small and unique edits, they were not included in the scripts.

	This patch also cleans up other minor issues that must be addressed
	before reverting to classic command substitutions and updates
	"shellcheck" directives to account for changes in this script and the
	change in "shellcheck" towards reporting individual portability issues.

	2021-05-26  Jacob Bachmeyer  <jcb@gnu.org>

	config.guess: automatic fixups after previous automated patch
	This patch was generated using the following command:

	      -e '/="[^"]\+"[[:alnum:]]/s/="\$\([^([:space:])]\+\)"/=${\1}/' \
	      -e \
	'/\$(echo[^|]\+|/s/\([^[:space:]]\)[[:space:]]*|[[:space:]]*sed/\1 | sed/g'

	* config.guess: Remove unneeded quotes in other variable assignments,
	standardize spacing for "echo ... | sed" substitutions.

	2021-05-26  Jacob Bachmeyer  <jcb@gnu.org>

	config.guess: remove unneeded quotes and factor command substitutions
	This is further cleanup and simplifies some constructs that can confuse
	Emacs' syntax highlighting while generally reducing required quoting.

	This patch was generated using the included GNU Awk program.

	* config.guess: Remove unneeded variable quotes and factor out command
	substitutions when setting GUESS.
	* patch-3.gawk: Store the tool that produced the automated patch.

	config.guess: manual fixups after previous automatic patch
	* config.guess: Adjust a few "leftover" cases that the tool could not

	config.guess: use intermediate variable with uname results
	This will allow quoting to be significantly simplified in another

	config.guess: fix shellcheck warning SC2154
	While, according to Plan 9 documentation, the environment variable
	$cputype is set to the name of the kernel's CPU's architecture,
	shellcheck warns that cputype is referenced but not assigned.
	Be on the safe side and do not use cputype if it is not defined
	or empty.

	* config.guess (*:Plan9:*:*): Fix shellcheck warning SC2154.

	2021-05-24  Dmitry V. Levin  <ldv@altlinux.org>

	config.guess: remove redundant quotes in case commands
	According to the GNU Autoconf Portable Shell Programming manual,
	the Bourne shell does not systematically split variables and back-quoted
	expressions, in particular on the right-hand side of assignments and in
	the argument of 'case'.

	The change is made automatically using the following command:
	$ sed -E -i 's/(\<case )"(\$[^"]+)"( in\>)/\1\2\3/' config.guess

	* config.guess: Simplify case commands by removing quotes around the
	argument.

	config.guess: simplify exit status workaround on alphaev67-dec-osf5.1
	Commit 29865ea8a5622cdd80b7a69a0afa78004b4cd311 introduced an exit trap
	reset before exiting to avoid a spurious non-zero exit status on
	alphaev67-dec-osf5.1.  Simplify that code a bit by moving the exit trap
	reset around.

	* config.guess (alpha:OSF1:*:*): Reset exit trap earlier.
