Yes. This is really just a case of trying to automate this so that the user
has less trouble. You have no idea how many tech support calls we get which
are solved by, "make sure that gdb can find everything it needs". From what
I understand, RPATH is supposed to be THE ordained way of making sure that
the linker can find it's libs so perhaps we need to add one more case to
solib_open() where it looks through RPATH. I'm thinking that it can't hurt
and might help. Certainly it will be helpful on native debuggers.
