That is not the behavior I see right now with omap3_beagle, for example.
It gives me u-boot.img and MLO (along with u-boot.bin and
spl/u-boot-spl.bin), both with and without O=.  That's why I suggested
looking at the file I said because that's what controls making
u-boot.img be an always built target, for omap3 boards with SPL.
