Hi Christian, Ross or some else to whom it may concern ,

Can you also have a look at:
https://patchwork.yoctoproject.org/project/oe-core/patch/[email protected]/

It simply makes sure LICENSE files are always present.

Thanks,
Jeroen

If a gomod is omitted with a PACKAGECONFIG option its license file
doesn't get extracted to the gomod cache dir and hence do_populate_lic
will complain that the license file isn't found. This adds a task
do_extract_lic after do_compile and before do_populate_lic to make
sure the license files are extracted in such a case.

v2:

- drop bb.utils.mkdirhier(os.path.dirname(cachefile)), extract
   will create it.
- fix typo in the commit msg, it is do_populate_lic
