Comment # 6 on bug 99013 from Christoph Haag

The build system already uses llvm-config --version which contains the revision
for svn versions. Of course it breaks when you update llvm without rebuilding
mesa, and you probably don't want to run llvm-config --version every time the
mesa libraries are loaded, so yea...

Anyway

Thanks, that fixed it on my llvm 3.9.
