That doesn't seem to be right. I'm seeing this build error with LLVM SVN
revision 331085 (basically a build of the source package from [0]). But when I
look at the log of the failing Mesa build of commit 8b7358fe43 I'm seeing:

which clearly includes "-lclangFrontend" and I verified, that
clang::FrontendTimesIsEnabled is actually in that library:
> FrontendTiming.cpp.o:

Or am I misreading something here?
