[libvirt] gnulib compiler warning detection broken on RHEL5 autoconf

I was wondering why I didn't see any compile warnings from the broken
gnutls code on RHEL5 when I noticed that we were building without any
compiler warning flags at all.

It seems configure fails on RHEL5 vintage autoconf

  checking whether compiler handles -Wall... ./configure: line 75468: ${$as_gl_Warn+set}: bad substitution

I'm guessing it is the gl_WARN_ADD() macro that is at fault somehow.
