I was wondering, since the first thing usr.bin/clang/clang/Makefile does is import bsd.own.mk. It then imports src/usr.bin/clang/clang.prog.mk which again imports lib/clang/clang.build.mk.
The Makefiles in lib/clang/[subdir] import lib/clang/clang.lib.mk, which imports bsd.lib.mk, which in turn imports bsd.own.mk. But lib/clang/clang.build.mk is imported first, which is probably why src.conf isn't available in clang.build.mk. Would it be possible to swap the two .includes around in lib/clang/clang.lib.mk?
