I think the best solution is to 'svn export' svn directory to a temporary directory/folder:

svn export my-svn-directory tmp-pkg-directory R CMD build tmp-pkg-directory
R CMD check --as-cran ...

The two advantages of 'svn export' that it (1) strips the .svn specific files, and (2) it really exports only those files that really are under version control. More often than once I have had some non-svn files in my svn directory so that *my* version of the package works, but the one actually in subversion fails.
