We still need a slight patch to Unladen to make the OProfile support work

need to patch up the build system to pass LLVM's full flag set through to
embedding
apps.

This was previously blocked on using llvm-config to obtain the necessary
flags; that
support was added in r981.

Basic oprofile support was added in r986:
