Setting CC/CXX/CPP and such in src.conf doesn't work, at least not for
all Makefiles in world.  There are still many of them that don't do the
right thing, picking up CC values from sys.mk and/or make.conf instead.

The trickiest one is Makefile.inc1, which does some special magic, and
isn't really a normal BSD Makefile anyway. :)

I've got a git branch with some experiments to have all the compiler
settings read from src.conf instead of make.conf, but I didn't finish it
before some other work took precedence...
