gcc8: move admonition about PKGREVSION next to the entry (NFC)

(Not that that makes any difference when automated tools are involved.)

gcc*: Disable FORTIFY on Linux only

lang/gccX: switch from USE_LANGUAGES=c99 to USE_CC_FEATURES/FORCE_C_STD.

gcc*: replace gnarly cargo-culted extract logic with EXTRACT_ONLY

*: recursive bump for Python 3.11 as new default

lang/gcc*: USE_TOOLS+=sed, not sed:run.

As far as I can tell, gcc needs this at build-time, not at run-time.

https://mail-index.netbsd.org/tech-pkg/2023/06/02/msg027624.html

lang/gcc*: Set CC_FOR_BUILD and CXX_FOR_BUILD if cross-compiling.

Verified gcc6 and gcc7 cross-compile on NetBSD, at least if the
gcc-fortran option is disabled.  gcc8 and gcc9 have trouble because
of python (why do these have a full dependency on python?); gcc10 and
gcc12 are missing gcc/config/mips/netbsd64.h; gcc12 and gcc13 have a
cross-compile bug with missing __LIBGCC_*__ macros -- but in any
case, setting CC_FOR_BUILD and CXX_FOR_BUILD is obviously necessary
for cross-compilation.  Conditional on USE_CROSS_COMPILE, so no harm
to native builds.

gcc8: fix some pkglint

gcc8: update to 8.5.0

one year of bugfixes

*: Revbump packages that use Python at runtime without a PKGNAME prefix

*: recursive bump for perl 5.36

gcc8: deconditionalize CHECK_RELRO_SKIP

as hinted by mef's recent bulk build, it appears to be more complicated
than simply a matter of bootstrapping

lang/gcc*: skip some RELRO checks when --disable-boostrap

This relates to the case when GCC is built using clang host CC. In that
case the runtime libraries are not built with RELRO for some reason.

for the gcc*-libs/ packages, mark them as RELRO_SUPPORTED=no unconditionally.
RELRO status depends on how the parent gcc package was built so we don't
need nor care about the RELRO status here.

gcc*: Unsafe for MKPIE. Reported by tnn.

gcc*: disable full bootstrap when the pkgsrc compiler is clang

LLVM versions >= 12 cannot currently correctly compile gcc stage 1 because
GCC assumes references to certain symbols like "ix86_isa_flags" will be
optimized away.
Details: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=255760

*: recursive bump for perl 5.34

GCC does not support Darwin-*-aarch64.

lang/gcc{6,7,8,9,0}: call SUBTARGET_INIT_BUILTINS on sparc* too

While here point out that the aarch64 equivalent patch was sent upstream.
Bump PKGREVISION. fix gcc*-libs PKGREVISION accordingly.

Fixes PR pkg/55992: math/blas fails on NetBSD/sparc64
Fixes report by Connor McLaughlan on pkgsrc-users

Revbump packages with a runtime Python dep but no version prefix.

For the Python 3.8 default switch.

Fix grammar in a comment in gcc* Makefiles

gcc*: Skip CTF for gengtype, causes hangs.

gcc8: Pass default RPATH like gcc7, bump PKGREVISION

*: bump PKGREVISION for perl-5.32.

lang/gcc8: remove no-op SUBST block

The file gcc/Makefile.in does not contain GCC_TARGET_MACHINE, and there
is no patch that adds this placeholder. The related words that actually
appear in Makefile.in are -DTARGET_MACHINE, $(target_noncanonical),
$(target), $(real_target_noncanonical).

gcc8*: update to 8.4.0

Changes not found. ~ one year of bug fixes on top of 8.3.0.

gcc8*: reduce differences to gcc7*

This also fixes RELRO builds.

Bump PKGREVISION.

gcc8: surround use of zlib/builtin.mk with CHECK_BUILTIN

gcc8: only use the system zlib if it is really the system's and not pkgsrc

GCC doesn't provide any flags for linking with zlib in non-standard
locations. Also, doing so could plausibly lead to cyclic dependencies.

gcc8: skip portability checks under contrib/

lang/gcc8: disable check for unknown configure options

GCC has several configure scripts that all differ in their supported
options.

all: migrate several HOMEPAGEs to https

pkglint --only "https instead of http" -r -F

With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.

This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.

lang/gcc8: fix DESCR

gcc-8.3 is not a development version.

Bump PKGREVISIONs for perl 5.30.0

gcc8: gcc8-libs: Upgrade to 8.3.0

GCC 8.3

This is the list of problem reports (PRs) from GCC's bug tracking system that are known to be fixed in the 8.3 release. This list might not be complete (that is, it is possible that some PRs that have been fixed are not listed here).
Windows

https://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=RESOLVED&resolution=FIXED&target_milestone=8.3

    A C++ Microsoft ABI bitfield layout bug, PR87137 has been fixed. A non-field declaration could cause the current bitfield allocation unit to be completed, incorrectly placing a following bitfield into a new allocation unit. The Microsoft ABI is selected for:
        Mingw targets
        PowerPC, IA-32 or x86-64 targets when the -mms-bitfields option is specified, or __attribute__((ms_struct)) is used
        SuperH targets when the -mhitachi option is specified, or __attribute__((renesas)) is used
    GCC 8 introduced additional cases of this defect, but rather than resolve only those regressions, we decided to resolve all the cases of this defect in single change.

PKGREVISION bump for anything using python without a PYPKGPREFIX.

This is a semi-manual PKGREVISION bump.

gcc8: Fix gcc/target/87221 better.
Link PIE executables with crtbeginS/crtendS on NetBSD.

Bump PKGREVISION

Add -fPIC to CRTSTUFF_CFLAGS to fix --enable-pie when building firefox

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87221

With this gcc8 can build a working firefox on NetBSD-8/amd64

gcc8: Add same SunOS mkostemp workaround as others.

Update to 8.2.0

Changelog:
This is the list of problem reports (PRs) from GCC's bug tracking system
that are known to be fixed in the 8.2 release. This list might not be
complete (that is, it is possible that some PRs that have been fixed are
not listed here).

General Improvements
    Fixed LTO link-time performance problems caused by an overflow in the
      partitioning algorithm while building large binaries.

Language Specific Changes
C++
GCC 8.2 fixed a bug introduced in GCC 8.1 affecting passing or returning
of classes with a deleted copy constructor and defaulted trivial move
constructor (bug c++/86094). GCC 8.2 introduces -fabi-version=13 and makes
it the default, ABI incompatibilities between GCC 8.1 and 8.2 can be
reported with -Wabi=12. See C++ changes for more details.

Target Specific Changes
IA-32/x86-64
    -mtune=native performance regression bug84413 on Intel Skylake
      processors has been fixed.

Recursive bump for perl5-5.28.0
