branch-1-4 AIX, HP-UX fix

[libtool-patches]

1. I've passed the AIX fix by Dan McNichol from IBM and he's OK with it.
   This patch is also needed on HEAD. Once this patch is in,
   LDFLAGS="-Wl,-brtl" ./configure will get AIX with and without gcc
   in the 1.4 branch to pass *all* tests.
2. The patch to shl_load syncs up this section of code with HEAD.
