description:
On platforms that have neither a builtin groff nor builtin curses
we can end up with a circular dependency:

ncurses -> groff -> netpbm -> flex -> bison -> gtexinfo -> ncurses

ncurses may depend on groff because of USE_TOOLS+=tbl.
Break the circular dependency by using --without-manpage-tbl
if there is no tbl(1) available and we're unable to build
groff because of missing curses.
