$Revision: 1.3 $

This proposal defines the following variable modifications in the interest
of cleaning up unused or rarely used features of bsd.pkg.mk which may be
accomplished by cleaner means.

- NO_WRKSUBDIR:  Removed.  Replaced with WRKSRC=${WRKDIR} in appropriate
  pkgs.

- ALL_ENV:  Environment variables passed to all third party scripts and
  Make invocations.  Implicitly added to CONFIGURE_ENV, MAKE_ENV, and
  SCRIPTS_ENV.

- PATH will be overridden in ALL_ENV, to insert ${LOCALBASE}/bin and
  ${X11BASE}/bin _before_ the existing $PATH, to ensure that appropriate
  progrms are found during package configuration.
