We discussed this briefly some time ago [1], and my take was this debug
information is not a hard requirement.  And it is not really consistent
over architectures where aarch64 defines dl_aarch64_cap_flags, but does not
add the debug print hook.

If you think we should really keep it, maybe then keep the removal of
the ones that are either empty (alpha, csky) or unused (aarch64, x86) along
with _dl_hwcap_string (which is unused since the glibc-hwcap), and
them move dl_<arch>_cap_flags out of _rtld_global and make it local 
to _dl_procinfo.
