I also did not succeed building clang in obj-dir.
Only after "mv llvm/tools/clang llvm-build/tools" it started to work.
I do not remember in detail what else more I had to do. Possibly
some hacking of Makefile's BUILDDIR?

I guess Reid as the father of the build system can say why this doesn't work.

Building clang just like the rest of llvm would be a Good Thing!
