Yes I though about a "BUILD_DEPENDS_SENSITIVE" or something like that, but it
means that PORTREVISION cannot be handled anymore via bsd.port.mk but should go
via a script (make(1) cannot do math as far as I can tell).

Also we need to be able to determine  which of the BUILD_DEPENDS requires to
bump the revision.

Last it means we have a state of the last build for each packages somehow which
by design does not exist (for us) but do exist for Arch and most of the linux
distribution.

Note: If we could do it, it will solve the specific case of "if some of my build
dependency changes then I need to rebuild the packages" which is a good first
step, but it does not solve the pb of the bundle modules.
