go-bootstrap and go for power64le architecture #15509
Description
Similar to #14900, this is a request to provide go-bootstrap and go for power64le.
There is a 1.13.8 port to power64le, so the majority of the work seems to have been done yet: https://dl.google.com/go/go1.13.8.linux-ppc64le.tar.gz
Currently, in verbose mode (and only then), the unknown arch is complained about:
