Does this still work with --enable-shared?  We deliberately exclude
TableGen from the shared library (since it defines top-level cl::opts),
and it looks like LINK_COMPONENTS causes only the shared library to be
linked to in --enable-shared mode.  Perhaps LLVMLIBS is the variable
that should be used here.
