PR bootstrap/32009
PR bootstrap/32161
* configure.ac (CFLAGS_FOR_TARGET, CXXFLAGS_FOR_TARGET): Compute here.
* configure: Regenerate.
* Makefile.def: Define stage_libcflags for all bootstrap stages.
* Makefile.tpl (STAGE1_LIBCFLAGS, STAGE2_LIBCFLAGS, STAGE3_LIBCFLAGS,
STAGE4_LIBCFLAGS): New.
(CFLAGS_FOR_TARGET, CXXFLAGS_FOR_TARGET): Subst from autoconf, without
$(SYSROOT_CFLAGS_FOR_TARGET) and $(DEBUG_PREFIX_CFLAGS_FOR_TARGET).
(BASE_TARGET_EXPORTS): Append them here to C{,XX}FLAGS.
(EXTRA_TARGET_FLAGS): Append them here to {LIB,}C{,XX}FLAGS.
(configure-stage[+id+]-[+prefix+][+module+]): Pass stage_libcflags
for target modules. Don't export LIBCFLAGS.
(all-stage[+id+]-[+prefix+][+module+]): Pass stage_libcflags; pass
$(BASE_FLAGS_TO_PASS) where [+args+] was passed, and [+args+] after
the overridden CFLAGS_FOR_TARGET and CXXFLAGS_FOR_TARGET.
(invocations of `all'): Replace $(TARGET_FLAGS_TO_PASS) with
$(EXTRA_TARGET_FLAGS), $(FLAGS_TO_PASS) with $(EXTRA_HOST_FLAGS).
* Makefile.in: Regenerate.

* mh-ppc-darwin (BOOT_CFLAGS): Reenable.
2008-02-20 Paolo Bonzini <bonzini@gnu.org>
* doc/install.texi: Correct references to CFLAGS, replacing them
with BOOT_CFLAGS. Document flags used during bootstrap for
target libraries.
