BUILDING says this isn't necessary (although I won't argue that it
isn't an effective workaround).

     TOOLDIR     Directory to hold the host tools, once built.  If specifie=
d,
                 must be an absolute path.  This directory should be unique=
 to
                 a given host system and NetBSD source tree.  (However, mul=
ti-
                 ple targets may share the same TOOLDIR; the target-depende=
nt
                 files have unique names.)  If unset, a default based on the
                 uname(1) information of the host platform will be created =
in
                 the .OBJDIR of src.

                 Default: Unset.

and I don't think we should change this.  I do this all the time
(TOOLDIR=3D/usr/obj/auto-current/tools).  Last I checked the objdir ends
up not shared so non-machine-dependent host tools get built/installed
more than they needed to, but that's efficiency not correctness.

Sure, that would be good.

But until that's done, which is a lot of work, it seems that we have
different versions of host tools depending on the target machine.  I
think it makes sense to name them with the target; ugly beats broken.

I'd call it disklabel-$machine (or nbdisklabel-$machine) instead of
$machine-disklabel, to be parallel with nbmake-$machine.
