I have also worked on this for some time (oops. it's about 2.5 years since
I started...) I also have something "nearly working" and I do now know
how this should be done the right way...

I haven't looked at your patches yet (will do it during the weekend) but
I have some questions about how much you have tested it. My approach was
also to modify sunos.c,  and it was rather easy getting something to work
reasonable, but I found a couple of things that was "hard" without doing
major changes in sunos.c

- inderect/warning symbols didn't really work (but that may have been a
  bug in my code) This gave me big trouble with libc.

- I had problems supporing -x and -X with shared libs.

- I had problems supporting -Bsymbolic flags to ld (i.e. problems with
  ld.so.)

Generally, libc, libbfd and libstdc++ gave me _lots_ of problems even
though I though my ld was "bug free". Have you tested some of that above?
