Wow...talk about verbosity.  At least now I've ruled out any other arches
being selected.  I was pretty sure that they weren't because I had set a
break on set_solib_svr4_fetch_link_map_offsets and it was only called by us.
Since that's the only interface to change the lmo function, it would seem
like it has to be happening in the solib-svr4.c file somewhere.  That's why
I was hoping to set a watchpoint.
