I recommend adding an extra 16 long over what your really
need.  This way if any new extentions and/or anything else
that needs to be put into jmp_buf, there's room. :)

What are the issues?  [BTW, I do have a Linux ARM machine with
shared libraries for anyone who's interested in COMPAT_LINUX work.]
Isn't more of just supporting the relocs exported by ld?

This I can do.

I would imagine this falls out of bfd.
