Nice. I'd however change the patch behaviour to the following:

- patch-* from FreeBSD
- EXTRA_PATCHES from FreeBSD
- local patches

Your patch looks like it appleis the out-of-tree patches prior
to any EXTRA_PATCHES defined by the port itself. This should not be
the case, in my opinion. Locally managed patches should always come
last to ensure that all FreeBSD/maintainer-specific bits have been
applied and the local changes are just added on top of those.
