description:
don't give NetBSD.dist.tmp any inputs, as then it won't rebuild ever
unless they change, and we want to rebuild based upon what inputs are
present, not when they were last touched.

this fixes update builds that switch options that change the dirlist
like MKX11 or MKCOMPAT, restoring a portion of rev 1.14.

note that some opertions like turning off MKX11=yes will also require
a fresh DESTDIR, in addition to this fix.  there may be more issues
remaining, but i am now able to enable MKX11=yes successfully without
any other change.
