The xorg server is somewhat sensitive to certain gcc versions combined
with -Os, particularly for ARM and MIPS, typically in the form of the
following symptom/error:
(EE) Segmentation fault at address 0x0
(EE)
Fatal server error:
(EE) Caught signal 11 (Segmentation fault). Server aborting
Force -O2 to work around this problem - for a target rootfs that uses
X11 the tradeoff is minimal since a sample/test image for qemu vexpress
with X11 + xinit + xterm + twm + xclock + gtk2 with demos is 60+ MB.
And it's less complicated than trying to find all of the bad
combinations.
Fixes bug #8436.
