[yocto] any point in a single machine recipe using a machine-specific file?

  ok, now we're getting somewhere -- so it would be *strongly*
*encouraged* to make all of these bbappend files machine-specific?
that is, if you want to avoid potential confusion down the road. i'm
still a bit queasy on the idea that you'd include so many layers that
this might be an issue but ... whatever. i mean, if i wasn't
specifically building for an rpi, i can't imagine why i'd include the
meta-rpi layer.

  huh, you're right, i'd never noticed that.
