cscope: Link tinfow instead of tinfo
b90780d 
Whenever attempting to use any ncurses functionality within cscope, a
page fault would result within the ncurses library.

    Program received signal SIGSEGV, Segmentation fault.
    0x00007ffff7fad3cf in termattrs_sp () from .../lib/libncursesw.so.6
    (gdb) bt
    #0  0x00007ffff7fad3cf in termattrs_sp () from .../lib/libncursesw.so.6
    #1  0x00007ffff7faa794 in _nc_setupscreen_sp () from .../lib/libncursesw.so.6
    #2  0x00007ffff7fa614c in newterm_sp () from .../lib/libncursesw.so.6

    #4  0x00007ffff7fa2970 in initscr () from .../lib/libncursesw.so.6
    #5  0x0000000000403dc2 in main (argc=<optimized out>, argv=0x7fffffffcea8) at main.c:574

This is due to a conflict between libtinfo.so and libtinfow.so. Both are
linked into cscope:

    $ ldd $(which cscope)
    /bin/bash: .../lib/libtinfo.so.6: no version information available (required by /bin/bash)
        linux-vdso.so.1 (0x00007fff5dbcb000)
        libncursesw.so.6 => .../lib/libncursesw.so.6 (0x00007f435cc69000)
        libtinfo.so.6 => .../lib/libtinfo.so.6 (0x00007f435cc2c000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f435ca29000)
        libtinfow.so.6 => .../lib/libtinfow.so.6 (0x00007f435c9e8000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f435cca7000)

Specifically linking libtinfow.so instead of libtinfo.so resolves the
issue.
