[PATCH 0/5] x32 support

[Ahelenia Ziemiańska]

This patchset essentially boils down to:
  (a) disabling -mcmodel=large, and
  (b) allowing ELFCLASS32 in x86_64.

I've also updated the autotools scripts so they detect x32 correctly
and fixed some warnings.

Ahelenia Ziemiańska (5):
  config: update to latest config.{sub,guess}, install-sh
  configure.ac, arch/x86_64: handle x32 as subarch of x86_64 and don't
    specify -mcmodel=large there
  i386/kexec-mb2-x86.c: cast ints to uintptr_t before pointers to avoid
    warnings
  i386: fix string formatting-related warnings
  x86_64: allow ELFCLASS32 for x32 support
