FD-PIC patches for uClibc

[Bernd Schmidt]

No one made further comments regarding the second set of patches, so
I've now made another pass over them to fix a few problems and style
issues, and checked them in.

A few minor issues remain to be resolved to get the Blackfin support
100% working, and the FRV needs attention as well.  I'll be working on
getting Blackfin support complete in the near future.
