USE_DESTDIR broken on packages without PKG_DESTDIR_SUPPORT

[David Brownlee <abs%absd.org@localhost>]

        I have USE_DESTDIR=yes set in mk.conf to make PKG_DESTDIR_SUPPORT
        aware packages build using destdir. This is now failing for
        packages without PKG_DESTDIR_SUPPORT.
        Is there a different way of doing this now?

(/pkgsrc/databases/pear-MDB2_Driver_pgsql)54# make
WARNING: [license.mk] Every package should define a LICENSE.
ERROR: This package has set PKG_FAIL_REASON:
ERROR: USE_DESTDIR must be either ``yes'' or ``no''
*** Error code 1

(/pkgsrc/databases/pear-MDB2_Driver_pgsql)55# make show-var VARNAME=USE_DESTDIR
yes


        Thanks...
