Hi,
Unless anyone objects I'll commit this soon.
The list of relocations is taken from various sources, including
http://people.redhat.com/drepper/tls.pdf
http://wiki.parisc-linux.org/ThreadLocalStorage
I can't find a specification document for powerpc / m68k so I've just use
binutils sources as a reference.
Thanks,
Nick
