[PATCH 0/7] PowerPC64le multi-arch

[Alan Modra <amodra at gmail dot com>]

powerpc64le is only supported on power8 hardware and later, so it
doesn't really make sense at the moment to build glibc for powerpc64le
with --enable-multi-arch.  You get a whole lot of code for older
processors that won't ever be executed, bloating glibc, and needless
ifunc indirection.  This patch series sets about fixing this for
powerpc64le.  I haven't made it possible to select any base
architecture, as that looked like too much work to tackle, but
hopefully I've written this patch in a way that could be extended.

The first few patches tidy assorted nits, the last one is the meat of
the patch.

Alan Modra (7):
  [PowerPC64] Don't define __GI_ variant of isnan for static lib
  [PowerPC64] Remove duplicate define in stpncpy-power8.S
  [PowerPC64] Wrap str{,n}cmp-power{8,9}.S in IS_IN(libc)
  [PowerPC64] Tidy strcasecmp_l-power7.S symbols
  [PowerPC64] strncase_l-power7.c should use strncase_l.c
  [PowerPC64] sysdep.h doesn't need to be included in multiarch files
  [PowerPC64] Multi-arch powerpc64le base arch is power8
