glib-2.0 2.21.4: add armv6 atomic ops, this fixes 100% utilization hangs when doing DSP based GStreamer playback

GLIB by default uses ARMV5 instructions for emulating atomic operations and this patch (derived from https://stage.maemo.org/svn/maemo/projects/haf/trunk/glib/debian/patches/25-gatomic.patch) make use ARMV6 atomic instructions instead. CPU goes into "sched_yield" while loop during hang - due to a race condition triggered by  high rate context switching while running DSP plugins.
