The above cleanup broke linkage support on systems without weak or
one-only support.  There is an AIX PR on this.

I have access to an old version of the HP linker code which was placed
into the public domain.  This has been useful in a number of cases in
diagnosing problems.

I do test HP-UX 10.20 and 11.00, but not on a daily basis.  As far as
I know, there aren't any significant problems with 4.0.0 beyond that
present in 11.11.

I currently have PHSS_30968 on the HP-UX 11.11 system that I test
on.  A linker patch is needed on 11.X to successfully build libstdc++
but I assume you are aware of that.  I'll give your change a try
when my current build completes.

Dave
