http://berklix.com/~jhs/src/bsd/fixes/FreeBSD/ports/gen/devel/autoconf-wrapper/Makefile.REL=ALL.diff

Moved from Makefile.REL=ALL.diff to Makefile.REL=8.0-RELEASE.diff
as 6.2-RELEASE has no devel/autoconf-wrapper just 
autoconf213/ autoconf253/ autoconf259

Allow repeated top makes calling lots of dependencies that call
make install reinstall package package-recursive etc
to survive without error

This is '-' should also be prepended to at least all of
6.3-RELEASE 6.4-RELEASE 7.1-RELEASE 7.2-RELEASE 7.3-RELEASE 8.0-RELEASE current
