Same here.  I'd so much love to just have ARCH an CROSS_COMPILE in my
.config for cross-builds.  Oterwise I keep forgetting them, or keep
forgetting to unset CROSS_COMPILE and will just waist a lot of time
either way.

The fact the the .config files even mention what architecture they are
for in a comment but don't make use of that information is just hostile
to users.
