Re: [libvirt] [PATCH] build: use the gnulib version of the .m4 files when present

prevent aclocal to prefer .m4 files under m4/ to the version provided by gnulib. I have noticed this after './configure --help' gave me two different versions of "--enable-threads". This was caused by aclocal that preferred the version of lock.m4 provided by autopoint instead of using the newer version distributed with gnulib.
