Hi,

starting with commit 1616d034b61622836d3a36af53dcfca7624c844e
the output was corrupted on some platforms as _dl_procinfo
was called for every auxv entry and on some architectures like s390
all entries were represented as "AT_HWCAP".

This patch fixes the condition which determines if _dl_procinfo
is called and adjusts _dl_procinfo implementations which assumed
that they are only called for AT_HWCAP or AT_HWCAP2.

A further question is if we should always call _dl_procinfo without a 
condition and let it decide if it is able to print an entry or if it 
should be printed with help of the auxvars list?

Okay to commit?
Once it is committed I would also backport it to glibc 2.29 release branch.

Bye,
Stefan
