These files should be copied to /usr/local/{bin/lib} if you
wish to install the new make (bmake) without re-compiling it.
You can't put the *.mk files in /usr/local/lib/mk anywhere else
because that pathname is hardcoded into the bmake(1) executable
in this bin/ directory.  If you wish to install it elsewhere,
you'll have to build and install it from the sources.  See the
installation guide if you wish to do that.
