bootstrap script uses source files from pkgsrc/devel/bmake/files
for "bmake". Remove all of bmake source from this bootstrap. Keep bootstrap/bmake/mk -- copy to files-mk (so the bmake "boot-strap" doesn't notice the mk*). This was tested on DragonFly, NetBSD and some on Linux. Hopefully all the fixes to boostrap's bmake are included in devel/bmake/files. Note that the "mk" files is still not using devel/mk-files.
