configure: Disable gstreamer support if headers are not compatible with build environment. (try 2)

When building a 32-bit wine in a 64-bit build environment with
default glib headers (gstreamer uses glib.h), glib 64-bit types
(such as gint64 and guint64) are not properly defined, causing
many compiler warnings and most likely a broken winegstreamer.dll.

Although both gstreamer and glib are included in the ia32-libs
package (on Ubuntu, and possibly others), the lack of a proper
glibconfig.h makes the gstreamer headers unusable for 32-bit

try 2: use AC_COMPILE_IFELSE instead of AC_CHECK_SIZEOF.
