Convert gnu to using SRCTOPPrefer SRCTOP over CURDIR/../../contrib, etc. However, retain the "upone level" instances of ../ because they are really relative to thispart of the tree and not a means to find the root of the tree.

8a5f4396 - META_MODE: Avoid changed build command every build.

Tue, 12 Apr 2016 02:45:19 +0000

META_MODE: Avoid changed build command every build.Because the file is generated with -f using another Makefile, 2different Makefiles are trying to handle the .meta file for thetarget. The obvious .NOMETA_CMP or .NOMETA on the ${MAKE} targetsdon't work as they are very limited in scope in bmake. Using.PHONY fixes the problem and ensures that the ${MAKE} commandis always ran to check if it is outdated in the sub-make.An example of the problem in gnu/lib/libgcc (with make -dM): /usr/obj/root/git/freebsd/gnu/lib/libgcc/tm.h.meta: 2: a build command has changed TARGET_CPU_DEFAULT="" HEADERS="options.h i386/biarch64.h i386/i386.h i386/unix.h i386/att.h dbxelf.h elfos-undef.h elfos.h freebsd-native.h freebsd-spec.h freebsd.h i386/x86-64.h i386/freebsd.h i386/freebsd64.h defaults.h" DEFINES="" /bin/sh /root/git/freebsd/gnu/lib/libgcc/../../../contrib/gcc/mkconfig.sh tm.h vs (cd /root/git/freebsd/gnu/lib/libgcc; make -f /root/git/freebsd/gnu/lib/libgcc/../../usr.bin/cc/cc_tools/Makefile MFILE=/root/git/freebsd/gnu/lib/libgcc/../../usr.bin/cc/cc_tools/Makefile GCCDIR=/root/git/freebsd/gnu/lib/libgcc/../../../contrib/gcc tm.h) Skipping meta for tm.h: .NOMETA (cd /root/git/freebsd/gnu/lib/libgcc; make -f /root/git/freebsd/gnu/lib/libgcc/../../usr.bin/cc/cc_tools/Makefile MFILE=/root/git/freebsd/gnu/lib/libgcc/../../usr.bin/cc/cc_tools/Makefile GCCDIR=/root/git/freebsd/gnu/lib/libgcc/../../../contrib/gcc tm.h) `tm.h' is up to date.Sponsored by: EMC / Isilon Storage Division List of files: /freebsd-12.1/gnu/lib/csu/Makefile

Fix installation of 32bit libraries after r288074.FILES is not used when LIBRARIES_ONLY is set, which is used to build andinstall the lib32 sysroot. All of the csu files do quality as "libraries"for this case so just undefine LIBRARIES_ONLY.This is still better than the previous realinstall handling as it doesnot hook into META_MODE properly.Sponsored by: EMC / Isilon Storage Division List of files: /freebsd-12.1/gnu/lib/csu/Makefile
