I have some local hacks in my tree that are Interix-specific, but can be
thought of as more general when packages are not assumed to be installed by
one user (where group permissions provide administrative status, rather than
just uid0).

The diff follows.  Of course, I'd like to choose a different name for the
symbol and put it into pkgtools/pkg_install/Makefile, rather than potting an
OS-specific symbol there.  Is there a preferred naming convention here?  I
was thinking "PKG_INSTALL_AS_NONROOT", but that sounds clunky.
