[PATCH] xconfig: use pkgconfig to find moc

["Yaakov (Cygwin/X)" <yselkowitz@users.sourceforge.net>]

From: Yaakov Selkowitz <yselkowitz@users.sourceforge.net>

Various schemes exist to allow parallel installations of multiple major
versions of Qt (4.x with the previous 3.x and/or the upcoming 5.x).
QtCore.pc includes a moc_location variable which should be a more reliable
way to find moc.
