First draft at making modules work again (loosely based on Rusty's original and

thoroughly broken ia64 patch).  Not all relocs are supported yet and the reloc
code needs to be cleaned up, but simply stuff like loading the palinfo module
works.  Also, linkage-stubs are optimized with brl for McKinley or better.
