Subject: Add option to build toolchain tarball

Add TARBALL_RESULT option that will produce a tarball of the final
toolchain to make it easier to deploy the toolchain to other machines.

The implementation uses `find | sort` instead of `tar --sort` because
this was introduced in GNU Tar v1.28, which is not available in some LTS
Linux distributions. This is  a variation of the command recommended
here: https://wiki.debian.org/ReproducibleBuilds/FileOrderInTarballs

Closes #1262
