Hmm, it should work like I described. I've built hundreds of packages
in that manner. When you run ./configure (an autoconf generated
configure, anyway), it should prefer CFLAGS from the environment and
propagate them to the generated Makefiles.

It's a wiki, so if you find it to be lacking, you can add information
there. That said, it is a little difficult to build up a fully
functioning Xorg installation from scratch. For some clues, you can
see the linuxfromscratch instructions.
It's a little behind the times, but it should give some clues. The
only part truly missing there is the external pixman library needed
