I previously thought that tinfo could only be a link to libncurses in modern ncurses installations. I was wrong. Now we check for ncurses, then check for tinfo. If tinfo is a link to ncurses, it is then not required to link against. But if libtinfo is providing tgetent, and not libncurses, then we must add it to LIBS as well. Also, kconfig shouldn't hardcode -lncurses, it should use what is in $(LIBS). Signed-off-by: Bryan Hundven <bryanhundven@gmail.com>
