No, probably sprof.1.

I rerun the example programm in sprof(1), and it works in the sense,
that no error is reported. However, there is also no sensible output
either, just the headers.

But I don't know (I'm not a programmer) if this is a problem or just a
normal output.

I was not aware that there was an open question directed to me, sorry.
I'm not sure how to properly answer that from this e-mail, I hope it
is sufficient that I simply CC libc-alpha@sourceware.org?

This looks like the following with me (Debian stable):

helge@twentytwo:/tmp$ sprof -p libdemo.so.1
$LD_PROFILE_OUTPUT/libdemo.so.1.profile
Flat profile:

Each sample counts as 0,01 seconds.
  %   cumulative   self              self     total
   time   seconds   seconds    calls  us/call  us/call  name

Greetings

         Helge
