Make sure to set -march=<architecture> to something appropriate. -march
tells gcc what instructions it can use (so anything that doesn't support
these instructions will fail to run the resulting executable), whereas
-mtune only tells it to optimise for a certain processor type (but the
executable will continue to run on other processors as long as they
support the instruction set specified by -march).

You could try booting an XO-1.5 with mem=256M (append that to boot-file
in /bootpart/boot/olpc.fth) to simulate the memory pressure of an XO-1.
