Adding "perl" to BB_HASHTASK_WHITELIST would do exactly what you
describe so its at least possible although it doesn't cover a version
specific match which would probably be better as part of DEPENDS
handling.

Stopping it being machine specific is the first thing that needs fixing
though (I have a patch I'm testing for that one).
