Blackfin patch: Linker bits for FD-PIC (and ld.pot question)

Continuing the theme, this adds linker support for FD-PIC binaries to the Blackfin port.

Committed. Due to a shell accident, I also committed a change to ld/ld.pot (revision 1.27) which was apparently produced by configuring with --enable-maintainer-mode. I hope this is harmless; I don't know how these files are supposed to be handled in CVS. Should I leave it in?
