   This somewhat large patch adds in the hooks and Makefile changes needed
   to use the new solib interface. Testsuite results are similar to what we
   used to see with the old solib code (i tested hppa2.0w-hp-hpux11.11 and
   hppa64-hp-hpux11.11).

   Committed, please let me know if you notice any problems :)

Looks like you broke hppa2.0-hp-hpux10.20 :(.  Don't worry about it
though.  I'll fix it ;-).
