To prevent /usr/ports/Mk/bsd.*.mk from overriding it. You can
make it a normal assignment if you verify that it doesn't get overriden.
I think it can be a normal assignment.
The verify operation is the hard part :-) I was hoping someone
knew the answer. The ports structure is a twisty maze of backwards
and forewards compat hacks.
Ok I checked the usage of OSVERSION, and I have run tests on some
ports. It looks like we do not need to export OSVERSION since
the /usr/ports/Mk/bsd.port.mk file puts it into MAKEFLAGS, which
propigates the variable anyway.
OSVERSION is only used by the make infrastructure so anything that
references that variable would get it from make's global scope, or would
get it from a recursively called make which would have put it into the
env since it is in MAKEFLAGS.
