Looking through the Makefile scheme in llvm/clang, I can't find any place where
LDFLAGS is passed -L$PROJ_OBJ_ROOT (which I assume would evaluate out to
-L/sw/src/fink.build/llvm-clang-2.8-0/llvm_objdi/Release+Asserts/lib. I assume this needs to be
placed in front of any LDFLAGS passed to the build so that you end up with...
-L/sw/src/fink.build/llvm-clang-2.8-0/llvm_objdi/Release+Asserts/lib -L/sw/lib such
that the newly built libLLVMSupport.a is found before /sw/lib/libLLVMSupport.a from
the older llvm/clang installation.
