build 2.2-stable worlds on 3.0-current systems again. objformat calls getobjformat(), which doesn't exist in 2.2's libc. Technically there should have been a version number bump when it was added in -current. But it's used in so few places that it hardly seems worth that. Besides, the objformat program is very heavily used during a make world; it won't hurt to have it load a little faster.
