[PATCH] configure.ac: Be more helpful for users with mis-configured glib-2.0

[Andrew Eikum]

glib-2.0 ships different headers for x86 and x86_64, but pkgconfig
doesn't support returning different headers for a particular
architecture. Most distros will default to the 64-bit glib-2.0
headers, which will built winegstreamer incorrectly. We already have a
check for this mis-configuration, but we can print a more helpful
notice for users.
