SVN_REPO_PATH envvar during autoconf to use svnversion in there.

Some systems, like the Gentoo, copy the svn contents somewhere before
doing the autoconf, this may result in lack of .svn and thus minor
version "0".

This patch introduces the $SVN_REPO_PATH to say where the svn checkout
containing the ".svn" directory is.
