This variable has been apparently added in autoconf 2.60 which would explain why it's not in PMS. The idea is that datadir is the directory where program expects to find its own data while datarootdir is the one where 'global' data files are installed (l10n, desktop files, manpages etc.) Passing it normally wouldn't make a difference. It would for packages where we are overriding --prefix and that are installing datarootdir files other than info/man. So it's mostly a change for consistency rather than actual gain.
The value passed would be the same as for --datadir, i.e. "${EPREFIX}/usr/share"?
Yes.
