Lots of build fixes. This is turning out to be a very good 

idea since it forcefully codifing the ABI.  Since the shim
layer is no longer linked at build time in to the test suite
we can;'t cut any corners and get away with it.

Everything is working now with the exception of sorting
setting Module.symvers properly.  This may take a little
Makefile reorg.
