Not sure if anyone else has followed up on this, but could not find a
response so I will try.

This is indeed intentional to the extent that this is how GO works
when you are using "go mod" (which mender-artifact now does). We are
not first ones having these problems and there are several tickets
discussing this, e.g [1]. This should be applicable to any GO package
in Buildroot that uses "go mod"

There seems to be two ways to get around this,

1. Use 'go clean -modcache' command which should remove these files
2. Use "-modcacherw" flag of "go mod" which will make these files R/W
(this is only available after GO 1.14.x [2])

I am not sure how to best incorporate this into Buildroot.
