[Buildroot] [PATCH 12/21 RFC] package/gcc: include the extensa overlay in the legal-info output

[Yann E. MORIN]

the Xtensa overlay is combined with the gcc sources, so it must be
redistributed for proper compliance.

Add a post-legal-info hook that also installs the Xtensa overlay in the
legal-info output.
