[Buildroot] [PATCH v2 3/3] package/binutils: use our missing script to disable the doc

[Romain Naour]

Like for gdb, use our 'missing' script to workaround a build issue when makeinfo
is missing on the host.

This fixes the issue with binutils >= 2.26.

v2: Remove the script bundled with binutils sources an create a symlink to our
    customized 'missing' script.
