How else would it be done?  Make currently only looks for "obj" and
"obj.${MACHINE}", so either we need to change make to look in lots of
other places, or we need to use symlinks.

I don't like the idea of placing requirements on the environment,
especially as the required value of MAKEOBJDIR will vary from directory to
directory.

I suppose it might be possible to arrange that the system makefiles spot
when MAKEOBJDIR isn't set and re-exec make with it set appropriately, but
that sounds painful and doesn't handle changing it when crossing into
subdirectories.
