The version you select here needs to match ${PV} from one of the
available recipes in order to have any useful effect.  It looks like the
magic string for 2008q1 (see gcc-csl-arm-2008q1.inc) would be:

PREFERRED_VERSION_gcc-cross-initial = "4.2.3+csl-arm-2008q1-126"

and likewise for the others.  As things stand, it appears that you are
getting the regular gcc 4.2.4 selected and this one doesn't understand
cortex-a9.

If you wanted to try 2008q3 then that would be 4.3.2+csl-arm-2008q3-39.

That was close but, sadly, not quite on the button :-)
