I get this same problem on one particular Linux box. With
--with-curses-terminfo, it builds. Unfortunately, the autoconf code for
handling curses/terminfo is fairly opaque to me too.

At the top of terminfo.c, the following is used around the curses.h

#  include <curses.h>
# endif

So curses.h would be included. However, HAVE_CURSES_H is not defined.
This seems to be because the curses.h header check is inside this in
  case "$LIBS" in
This presumably fails because it uses just -ltermcap.

libtermcap.so is just a link to libncurses.so here. So how is that
situation otherwise handled? Should the HAVE_SETUPTERM test perhaps
similarly only be done if $LIBS = *curses*? Or can we perhaps safely
substitute -1 for ERR?
