Not even slightly.

Actually, I don't do any of that; I use build.sh.  And that's what the
documentation says.  From src/BUILDING:

   build.sh     Bourne-compatible shell script used for building
                the host build tools and the NetBSD system from
                scratch.  Can be used for both native and cross builds,
                and should be used instead of make(1) for any source
                tree that is updated and recompiled regularly.

Note the *should* in the last sentence.

I've made the point more explicitly several times: don't worry about
the best way to put it into the Makefile; worry about build.sh.
That's the recommended high-level interface to the build process.  And
build everything, just as we do for userspace.
