ncurses: make host-ncurses use host terminfo
Host GDB suffers a serious problem: pressing backspace (or ^W ^U or any other "delete" key) results in a plain space being printed instead, making the command prompt almost completely unusable. That's because it's using host-ncurses, which embeds a path for the terminfo database into the library itself. That path ends up being something like /home/hollisb/buildroot.git/output/host/share/terminfo, which obviously doesn't generally exist other hosts. ('relocate-sdk.sh' cannot and does not edit binaries like libncurses.so.6, so doesn't resolve this problem.) /usr/share/terminfo is a far better path to use, since it almost certainly exists on the host. Theoretically, it could be from a different ncurses version with incompatible terminfo database format, but this doesn't seem to be a problem in practice. (Future patches could address the theoretical problem if it actually appears in real life.) This change allows buildroot's host gdb, which uses ncurses 6.x, to work on RHEL5, RHEL6, and RHEL7, which all provide terminfo from ncurses 5.x.
