Okay, so the goal is a bit less ambitious than I had thought. I wonder
whether that's useful, because at least the problems Ostro and AGL (at
least as far as I understood it from lurking on their mailing list) had
only happened when trying to combine multiple BSP layers *and* actually
using the different machines in the same distro.

At least I'd find that useful - not sure about others ;-}

It's a bit more complicated than the existing tests, but I think it is
doable.

Does the BSP layer only modify machine-specific packages and only when
the MACHINE(s) defined by the BSP layer are selected? [yes/no]

The "only when" part is covered by the existing tests (because they keep
MACHINE constant). The missing part is comparing different MACHINE
sstamps.
