C++11 threading library

[Joel Sherrill]

Thanks.

GCC 4.8.2 was released on 16 Oct 2013. These are quite old and
we really need to get them off the site.

Most of the targets are using gcc 4.9.2 or 4.9.3 (not sure if
we bumped it yet).

Please use the rtems-source-builder (RSB) to build tools which
match the current source.
