[glib] Fix autoconf 2.68 warnings

[Dan Winship <danw src gnome org>]

commit 6f711a76cdd7eac3914542232526111a7b6bb053
Author: Dan Winship <danw gnome org>
Date:   Mon May 2 11:44:46 2011 -0400

    Fix autoconf 2.68 warnings
    
    autoconf 2.68 is very insistent that AC_LANG_SOURCE/AC_LANG_PROGRAM
    must be used in certain places, to avoid quoting/lack-of-quoting
    problems, or something. Fix.
