[Buildroot] [PATCH 0/2 v2] core/legal: support multi-version packages

[Yann E. MORIN]

Hello All!

This small series fixes our legal-info license check for packages that
have different versions and for which the licensing information has
changed between the versions, but the license files are named the same.

This is the case for Qt5 for example, where some license files for 5.6
are different than for 5.8, but are named the same.

Also fix checking the hashes of license files for host packages.

Changes v1 -> v2:
  - fallback to the main hash file is the per-version file does not
    exist,
  - fix checking hashes of host license files


Regards,
Yann E. MORIN.

[Buildroot] [PATCH 1/2 v2] core/legal-info: properly check hashes of license files for host packages

[Yann E. MORIN]

When called for a host package, we currently miss the hash file, because
it is named after the target package.

Fix that by using the package raw-name.

[Buildroot] [PATCH 2/2 v2] core/legal-info: use hash file from version sub-dir

[Yann E. MORIN]

When we have multiple versions for a package, and the licensing terms
depend on the version actually selected (e.g. like Qt5), storing the
hashes for those license files in the .hash file is broken: the infra
will ensure that all hashes for a file do match, which would not be the
case here.

We fix that by first looking for a hash file in the version sub-dir
first, and if that does not exist, then we use the main hash file.

Drop the useless intermediate variable 'ret'.

Update the documentation accordingly.

I took it for a test spin and this looks good to me.  I also uncovered a 
separate, but related question [1], with the exception case that qt5 is.
