[LLVMdev] Link error building llc

[Neale Ferguson]

With the TableGen problem circumvented the build proceeds quite well up
until:

These entry points are in modules that have been compiled and placed into an
archive. (e.g. llvm::createBURRListDAGScheduler is in ScheduleDAGRRList.cpp
whose object is placed in ./Debug/lib/libLLVMSelectionDAG.a).

I'm sure I've missed a configuration option or something trivial like that
but my newbie brain can't determine what it is.
