commit fd8a5352e3843dd787f7ba42912ea5cd04c3e434 (HEAD -> rpath)

    Fix ncurses to not add /usr/lib to rpath.
    
    There are three cases here:
    
    1) USES=ncurses or USES=ncurses:base and devel/ncurses is not present:
       use base, no need to add rpath as there is only one libncurses.so
       present, in /usr/lib
    2) USES=ncurses and devel/ncurses is present or USES=ncurses:port: use
       ports, and add rpath to LOCALBASE/lib so that the right one is picked
    3) USES=ncurses:base and devel/ncurses is present fail (it would warrant
       using -rpath /usr/lib, but it error's out during the sanity stage)
