Makefile: $ROVERLAY_TARGET_TYPE

ROVERLAY_TARGET_TYPE controls which files get installed:

when gentoo:
=> config/R-overlay.conf.install
=> no licenses file

when others:
=> config/R-overlay.conf.install.others
=> install files/licenses to $DATADIR/licenses

Also added a "generate-licenses" target for creating files/licenses.
