Is there any sane alternative for "do cross-architecture test builds"?

I do things like "make ARCH=i386 allmodconfig" myself, and I have to
admit that it's annoying that you have to then remember to do "make
ARCH=ii386" to do the actual build too, because otherwise Kcoinfig
will mess up the architecture, because it didn't make it into the
final simplified .config.

This is probably more noticeable with "defconfig" because then the
"ARCH=xyz" part has *other* effects too (ie it is also what says
*which* defconfig to pick).

So this is a bit of an annoyance, in that it's not trivial to just
"make the config for ARCH xyz" and then "make".
