I suspect that dld.sl is complaining about a missing section or possibly
the section to segment mapping.  This bug messes up the objc test results
when gcc is built with "--enable-shared".  However, other than the annoying
error message that doesn't tell you want's wrong, it doesn't seem to affect
actual code execution.  This error was around before the patch.  I think
that if we squelch this bug we should be able to build a shared libgcc
on hppa64-hp-hpux11.

That would be great.  Your test programs and analysis was a big help
in resolving the two previous bugs.
