[libvirt] [PATCH] build: update gnulib for FreeBSD build

[Eric Blake]

* .gnulib: Update to latest, for gcc 4.2 support and fixed FreeBSD tests.
---

Pushing under the build-breaker rule; this fixes the problems I found
on FreeBSD 8.2 during 'make check' with CFLAGS=-g.

* .gnulib b493832...bc8b4e9 (6):
  > pselect: reject invalid file descriptors
  > select: reject invalid file descriptors
  > ptsname: reject invalid file descriptors
  > hash-pjw-bare: new module
  > manywarnings: cater to more gcc infelicities
  > select, poll tests: Make setsockopt invocation effective.
