20? Debian's kernel package currently lists 17 architectures (11
source architectures) and 44 variants (excluding PREEMPT_RT and s390
install tape). (But 'only' 31 will be in the next release, as even
Debian is capable of letting go of an architecture.)

But, assuming a native build (a whole weekend's worth of fun on m68k!)
we already know the target architecture and most of the other
variations can be chosen automatically similarly to localmodconfig.
We already do something like that (choosing between the pre-built
variants) at distribution install time, after all.

This might work well for future releases; is there not a need to
make this work for past releases too?
