Work around the autotools problem with the 10.0 version.

With this, I can build various ports on a 10.0-CURRENT system without
hacking or hiding the version number.

This commit should be reverted when there is a cleaner fix in autotools
and/or ports/Mk/bsd.port.mk.

The original patch is from Ed Schouten but needed some additions.
