Remove support for building LLVM libraries into "relinked"
object files. Now we always build LLVM libraries into archives (.a files).
This makes the 'make' build work more like the cmake build, among other
things. Doing this exposed some latent circular library dependencies, so
I think that llvm-config wasn't quite right for .o files anyway.
