Hmmm, puzzled by this.

There are not described directly anywhere. We generally follow the
conventions used under HP-UX and described in the runtime documents
for HP-UX 10 and 11. This page has links to the HP runtime documents.

However, there are some differences because the GNU and HP tools
have somewhat different capabilities. For example, the HP assembler
and linker can handle a difference of a local code symbol and an
external code symbol. Thus, external pc-relative calls can be done
with the HP tools. This doesn't currently work with the GNU tools.
There's no PIE support under HP-UX, so I wouldn't be surprised if
other issues arise.
Just a note, I did an apt-get update on one of my systems last night
and this is caused problems with svn. See
