[Spice-devel] [PATCH xf86-video-qxl] configure.ac: support autoconf 2.63

[Alon Levy]

AC_CHECK_FILE(cond,[not-empty],[]) in autoconf 2.63 produces an empty
else that is illegal for bash, but forgoes the else when given a
AC_CHECK_FILE(cond,[not-empty]). 2.68 produces correct output on both,
so it's unaffected.
