Hmm, this also works fine here (on -current, with a basically empty
/etc/mk.conf):

$ mount | grep /usr/src
/a/src/nbsd/c on /usr/src type null (read-only, nosuid, nodev, local)
$ cd /usr/src
$ ./build.sh -O ~/temp2/obj -T ~/temp2/obj/tools tools
[...]
$ ./build.sh -O ~/temp2/obj -T ~/temp2/obj/tools kernel=GENERIC
===> build.sh command: ./build.sh -O /home/jukka/temp2/obj -T /home/jukka/temp2/obj/tools kernel=GENERIC

rm -f a.out [Ee]rrs mklog core *.core .gdbinit

Don't forget to run "make depend"

See the description of .OBJDIR in the make(1) manpage.
