Provided a POSIX sh is /bin/sh and gcc/cc is in your path this is a typical on linux for me:

sh -D /home/jmc/src/netbsd/obj_${m}/build -X /home/jmc/src/netbsd/xsrc -O /home/jmc/src/netbsd/obj_${m}/obj -T /home/jmc/src/netbsd/obj_${m}/tools -R home/jmc/src/netbsd/obj_${m}/release -m $m -U -N0 -x -u -j6 release

(i.e. replace $m with the specific machine you want to build)

You shouldn't need a specific bmake already installed or anything. /bin/sh
should be enough to get make going and then the bootstrapped make can get
the rest going.

If I remember it's dying on make's configure script about creating executables.
That's a pretty standard configure test. Change your to not nuke
the tmpdir and look in the config.log there to see why it's bailing (or send
me a copy of that config.log)
