Perhaps for the particular case of amd64 and i386.  But I would argue
that it'd be a bad idea, because amd64 and i386 are common enough that
it runs the risk of teaching people to think that cross-compilation
automatically Just Works, when amd64 cross-building i386 is one of the
few cases that work (the only one, until things like ppc64/ppc32 or
mips64/mips32 are also set up to Just Work).

In fact, I would argue that config and/or the kernel Makefile should
check that either the kernel is being built for the native architecture
or it is _explicitly_ cross-building.
