Yes, there are a number of libraries that don't have archive versions.
I believe libdld needs the dynamic loader.  Another library is librt.
We try to handle this problem in the LIB_SPEC define.

Advise using recent version.  There are no recent fixes affecting
GNU ld on hpux, but there have been some assembler fixes.

I've seen the segment issue but don't have a fix.  There's something
going wrong in the core code.  I think this is the main issue with
shared libraries.

I tried a full native build last night with GNU ld.  It failed with
a broken f951 compiler.  The problem is pc-relative calls are broken
(no stub, or incorrect offset to stub) when the call distance exceeds
the maximum branch distance for the 22-bit pc-relative relocation.
This should be relatively straightforward to fix.
