build-sys: Work around --with-rootprefix= (empty) not producing /

Browse Source 
Since we introduced AX_NORMALIZE_PATH, using --with-rootprefix=/ does
produce an empty string, but using --with-rootprefix= (empty) now
produces "." instead which is wrong.

Work around it until we can find a better solution for AX_NORMALIZE_PATH
upstream at autoconf-archive.
