I don't have a hppa.

The goal is to have lintian test that automatically tests hppa binaries
whether they are accidentally compiled with profiling enabled (which
shouldn't be the case).
The test already runs 'objdump --headers --private-headers -T', and this
is not easy to change (all other archs use that objdump).
Can you show us a dump like that with and without profiling, and
indicate which line is definitely the sign for profiling?
Thanks a lot,
