This commit adds the licensing information for the host-gcc-initial,
host-gcc-final and gcc-final packages.
For host-gcc-initial and host-gcc-final, instead of duplicating the
information, we use common variables coming from gcc.mk.
Of course for the target gcc-final, we use a different license than
for host-gcc-final, as it's the whole point of this series: be able to
describe that the target side of gcc is GPL-3.0 with linking
exception.
