atom-pc: work around gcc bug for core2
Fixes [YOCTO #853] Without these added optimization flags, the matchbox-panel (and possibly other) applications would segfault. This patch applies the changes to all machines derived from atom-pc.conf. [Tweaked by RP to apply to gtk+ only] Signed-off-by: Darren Hart <dvhart@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
