The powerpc still uses _dl_procinfo to print additional
information for LD_SHOW_AUXV and Peter express that this stil
useful in sme cases.  Since the current practice is to provide
such information on ld.so --list-diagnostics, move both
AT_HWCAP and cache geometry to loader option.

PS: I add the first patch from Wilco mostly to avoid unecessary
CI breakage, since this work is based on top of his patch.

Adhemerval Zanella (5):
  powerpc: Move AT_HWCAP descriptions to ld diagnostics
  powerpc: Move cache geometry information to ld diagnostics
  powerpc: Remove unused dl-procinfo.h
  Remove dl-procinfo.h
  linux: Prefix AT_HWCAP with 0x on LD_SHOW_AUXV

Wilco Dijkstra (1):
  Remove unused dl-procinfo.h
