Pull up following revision(s) (requested by martin in ticket #843):
	lib/libc/Makefile: revision 1.169 via patch
Only create and install the tags file for the normal libc (not any of the
compat copies), because we don't want it to be overwritten by the compat
copies. This was detected by the evbarm mkimage complaining.

#	@(#)Makefile	8.2 (Berkeley) 2/3/94
#
# All library objects contain sccsid strings by default; they may be
# excluded as a space-saving measure.  To produce a library that does
# not contain these strings, delete -DLIBC_SCCS and -DSYSLIBC_SCCS
# from CPPFLAGS below.  To remove these strings from just the system call
# stubs, remove just -DSYSLIBC_SCCS from CPPFLAGS.
#
# The NLS (message catalog) functions are always in libc.  To choose that
# strerror(), perror(), strsignal(), psignal(), etc. actually call the NLS
# functions, put -DNLS on the CPPFLAGS line below.
#
# The YP functions are always in libc. To choose that getpwent() and friends
# actually call the YP functions, put -DYP on the CPPFLAGS line below.
#
# The Hesiod functions are always in libc. To choose that getpwent() and friends
# actually call the Hesiod functions, put -DHESIOD on the CPPFLAGS line below.
