Description anb 2020-07-07 00:01:29 UTC

When go module is enabled, the directory under its cache has permission defaults to 0500, which prevent them to be removed by a non-priviledged account. 

Reproducible: Always

Steps to Reproduce:
Emerge any package inherit go-module, and doesn't remove temp files inside Makefile, e.g. dev-util/webhook, dev-util/github-cli.
Actual Results:  
Emerge failed with "portage.exception.PermissionDenied: [Errno 13] Permission denied" raised by prepare_build_dirs.py.

Expected Results:  
Emerge success.

Possible fix:

Go 1.14[1] introduced a new build option: -modcacherw, which could be added to the default GOFLAGS exported by go-module.eclass when under prefix, e.g.:

export GOFLAGS="-v -x -modcacherw"

though it requires go-1.14 at least.

does this have anything to do with Gentoo Prefix?
