[libvirt] [PATCH] build: use latest gnulib, for ignore-value fix

[Eric Blake]

* .gnulib: Update to latest.
---

Let's push this first, although that means you may want a v4
to move the include "ignore-value.h" line around.

* .gnulib b6d1430...cac3889 (8):
  > ignore-value: make header idempotent
  > GNUmakefile: handle "stable" target, not "major"
  > isnan: Add support for TinyCC
  > vasnprintf: Don't set errno to 0.
  > socketlib: Fix.
  > test-select-stdin.c: avoid warn_unused_result warnings
  > git-version-gen: do require git-VC'd files in cwd
  > argv-iter: omit nonconforming declaration
