[Buildroot] [PATCH 25/51] package/gcc: add licensing info for host variant

[Yann E. MORIN]

Add the full licensing terms known for gcc for the host variant.

This has so far no impact on the target variant that is not yet defined.
And in any case, the licensing terms for the target variant will be a
sub-set of those for the host, as only parts of gcc are installed on the
target.
