Help ncurses-native find terminfo on RHEL 6

[ CQID: WIND00405305 ]

When using ncurses from sstate cache it is not able to find terminfo
for screen on RHEL 6.  While RHEL 6 has /lib/terminfo, it is not
complete, the complete terminfo database is in /usr/share/terminfo.  This
results failure of programs linked to ncurses, such as menuconfig.
