xserver-psb: fix X server on emenlow when built with gcc 4.7.x

Browse Source 
Note: this patch has already been submitted against other BSPs,
originally submitted to oe-core by Gary Thomas.  I ran into this same
issue building MACHINE=emenlow on my own Z530 platform.  There are
likely others as well where this needs to be applied.

PR has been bumped.
