I think this is looking in the wrong direction: DESTDIR is almost
_never_ defined.  It exists for a corner use case, so much so that I
even don't think it will help to describe that use cased here.

My guess is something else is causing this.

Of course, I could be wrong, since I don't know enough about these
details of native compilation.  Apologies if I cause more confusion
than help.
