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 (BOOT_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. config: 2008-02-20 Paolo Bonzini <bonzini@gnu.org> PR bootstrap/32009 * mh-ppc-darwin (BOOT_CFLAGS): Reenable.
