[libvirt] [PATCH] maint: update to latest gnulib

[Eric Blake]

Incorporates fixes for cross-compiling to mingw on rawhide, where
gcc 5.1 changes detection of how to properly determine PRIdMAX.

* .gnulib: Update to latest, for mingw.

I've missed the freeze for rc1, but confirmed that this update
is rather minimal and should only affect mingw (in particular, it
will fix cross-compilation failure under rawhide with gcc 5.1).

As such, I won't push without review, but I also argue that the
changeset is small enough that it should be safe if we agree to
take it before rc2.

* .gnulib 875ec93...c26527c (5):
  > stdio: limit __gnu_printf__ witness to gcc 4.4+
  > error: use correct printf attributes on mingw
  > update from texinfo
  > inttypes: force correct mingw PRIdMAX even without <stdio.h>
  > stdio: fix probe on mingw under gcc 5.1
