Allow the use of $VPR_BASE_DIR instead of $prefix to be enabled through an environment variable.  All -config scripts will use this same environment variable unless we can come up with a clean way of passing the --basedir command-line option when running from within the global build. (One way of doing this could be to modify the relevant m4 macros.)
