I figured it out now. I was using a separate object directory, which
caused the relative file name arch/arm/configs/omap2plus_defconfig
not to be found and the KCONFIG_ALLCONFIG option to be silently
dropped. I misinterpreted the resulting .config file as one that only
got the choice statements wrong, when in fact it had not taken any
default values that I passed.

In short, everything's fine except for a missing warning message
when the allconfig snippet is not found, and me making a fool of
myself.

It did solve one of my problems in the end, so I'm happy.
