Comment (by cal@…):

 Attached a patch providing a generic callback mechanism (that might also
 be useful in other cases, I recall we also have an automatic dependcy on
 bsdmake `if ${build.type} == bsd` where this could be useful) and
 automatic compiler dependencies.

 To prevent duplicate dependencies in ports that already correctly declare
 a dependency we might add `depends_${type}-delete port:$compiler_port`,
 but that's just a cosmetic change now.

 Comments?
