I was thinking of a different approach entirerly. We can add the
following at the top of the recipe file:
python __anonymous() {
if "linux-raspberrypi-dev" not in
d.getVar("PREFERRED_PROVIDER_virtual/kernel"):
msg = "Skipping linux-raspberrypi-dev as it is not the preferred " + \
"provider of virtual/kernel."
raise bb.parse.SkipRecipe(msg)
}
(Hopefully gmail won't mangle that too much)
I've just tested it and it works fine as long as it's before the use
of ${AUTOREV}. If there's no objections to this approach I'll submit a
patch.
