[Buildroot] [pull request] provide and install libssp

[Yann E. MORIN]

Hello All!

This series attempts to cover the cases where libssp might:

  - be needed by some packages (mostly proprietary stuff), such as
    pre-built binaries that are dynamically linked to libssp.so.1

  - source but proprietary packages for which it is not possible to
    update/fix the build system, and which unconditionally want to
    link at build time against -lssp or -lssp_nonshared

So, this series:

  - adds a package that installs a fake, empty libssp.so.1 in target
    (for pre-built stuff) and a fake libssp.a and libssp_nonshared.a
    in staging (for unfixable proprietary source); this package is
    always built and installed, even if not doing SSP builds, because
    of pre-built proprietary stuff;

  - adds an option to external libs to specify whether they implement
    SSP via libssp or not (default: no, as previously).

This is not fool-proof tested, and only casual testing was done:

  - using an external toolchain without libssp.so

  - using the same toolchain with an empty file has libssp.so (just so
    as to trigger the mechanism)

Regards,
Yann E. MORIN.
