Wow, thanks Charles.  I keep thinking of DESTDIR as a non-used no-op on most
software systems ...

Ooh, don't tantalize me like that!  :-)

What if I were to propose the idea of having "make" look at an envariable
(e.g., "MAKESYSPATH", or maybe overload the old "VPATH"?) that, if set, would
tell "make" where to look instead of "/usr/share/mk" and (for syspath)
"/usr/share/mk/sys.mk"?  (i.e., overrule _PATH_DEFSYS{MK,PATH})

That way, one could do a build and not even need to overwrite/override
/usr/share/mk ...

Good, bad, just-plain-stupid?
