As it stands now, "make release" without EXPORTABLE_SYSTEM=1 is not
useful, as the resulting base set is polluted with crypto binaries
such as "ftp" and "ed".. Worse, it deletes the existing ${RELEASEDIR}.
I propose to change the behavior of "make release" when
EXPORTABLE_SYSTEM is not set and ..domestic exists, to _only_ build
the security set. Then you could build a release like so

  cd usr/src && \
  EXPORTABLE_SYSTEM=1 make build && EXPORTABLE_SYSTEM=1 DESTDIR=... \
    RELEASEDIR=... UPDATE=1 BUILD=1 make release && \
  make build && DESTDIR=... RELEASEDIR=... UPDATE=1 BUILD=1 make release
