OK; it's a known problem. At present, the only workaround is to
manually edit src/CMD/head/head, e.g.

	READLINELIB         = -lreadline -lncurses

and src/include/config.h, e.g.

	/* define if readline exists */
	#define HAVE_READLINE_READLINE_H 1

Unfortunately, it's far from clear as to which additional libraries we
should be checking for. Actually, it's fairly clear which libraries
are plausible (lib[n]curses, libtinfo and libtermcap), but the termcap
functions (e.g. tgetnum) are often provided by more than one of them,
and it isn't clear as to exactly which one we should choose.
