after the ipf library, since the ipf library depends on some functions
from the kvm library.
Fixes a build problem observed when building for sun2 (though I
won't claim understanding why this doesn't show up elsewhere).
* fix -j N parallel build issues
* support MAKEVERBOSE
* move NOxxx= to before <bsd.own.mk>
* remove unnecessary -ll (except for ipsend)
* remove unnecessary CPPFLAGS
* only build libipf.a (we don't need libipf_p.a or libipf_pic.a)
* fix dependencies upon libipf.a
(more could be done, but that requires fixing dist/ipf/*)
