compiler_rt fails to build in release_31 branch

Hi;

This is on Linux/x86-64, I get this at stage1:

make[2]: Entering directory /home/abuild/rpmbuild/BUILD/llvm/stage1/projects/compiler_rt' Makefile:6: make/[config.mk](http://config.mk): No such file or directory Makefile:7: make/[util.mk](http://util.mk): No such file or directory Makefile:16: *** Refusing to build with empty ProjObjRoot variable. Stop. make[2]: Leaving directory /home/abuild/rpmbuild/BUILD/llvm/stage1/projects/compiler_rt’
make[1]: *** [all] Error 1
make[1]: Leaving directory `/home/abuild/rpmbuild/BUILD/llvm/stage1/projects’
make: *** [all] Error 1

Interestingly trunk works fine but not the release_31 branch.

ping? Still fails on 3.1 branch.

Never mind correct directory name is compiler-rt with a dash not with an
underscore *doh*
