[Buildroot] host-ncurses: cannot find -lstdc++

Hello Mike,

It took me a second reading of your message to understand what you were
getting at.  I made the mistake of forgetting that NCURSES_CONF_OPT is
not used in host builds so I added HOST_NCURSES_CONF_OPT and set it to
generate tic, etc.

I don't imagine it will ignite much interest but for any RHEL5
developers experiencing problems building ncurses 5.7 with the host
ncurses 5.5 RPM, this patch should help.  Those without such problems
will curse it [see what I did there ;-) ].
