Yes, Warner pointed this out. Thanks.

Since we don't have GENERIC for arm, I think the path of least
annoyan^Wresistance is doing per-board builds. The build environments
are cheap - they are zfs datasets, destroyed/created on new build.

Well, no. :( The time-consuming part is the dependency chain for the
build. Such as, RPI-B needs python, gsed, and world+dog. BeagleBone
needs cross-gcc, and I'm sure other stuff.
It would be pretty cool if crochet could have a '-D' flag to 'show
missing dependencies for board specified'.
But, I do realize it's a PITA. :)
