I'm trying to build a -current mac68k on a 1.6 alpha, and
./build.sh -m mac68k -D /usr2/mac68k distribution
fails with:

nbmake: don't know how to make /usr/src.local/gnu/lib/libbfd/obj.mac68k/libbfd.a. Stop

nbmake: stopped in /usr/src.local/gnu/usr.sbin/dbsym

As far as I can tell, the problem is that dbsym's Makefile has a
DPADD+=         ${BFDDIR}/libbfd.a
line, but gnu/lib/libbfd/Makefile sets NOLINKLIB, so libbfd.a never gets
made.
