[PATCH 0/6] Fix -Os build

[Adhemerval Zanella]

This patchset fix the glibc build including tests with -Os.  I checked
with GCC 12 for all supported ABI and run a full make check for x86_64
and i686 without any regressions.

Adhemerval Zanella (5):
  posix: Suppress -Os warnings on fnmatch
  posix: Suppress -Os may be used uninitialized warnings on regexec
  rt: Initialize mq_send input on tst-mqueue{5,6}
  sunrpc: Suppress GCC -Os warning on user2netname
  x86: Fix -Os build (BZ #29576)

Martin Jansa (1):
  locale: prevent maybe-uninitialized errors with -Os [BZ #19444]
