Support for packages written in Go on powerpc_464fp

[Martin Kennedy]

Hi there,

I'm not quite sure why, but I'm not able to install e.g. Restic on my
MX60W (CPU: APM82181). I think it's because the golang package doesn't
include this architecture in its list of supported architectures?

Yet the HOST_GO_VALID_OS_ARCH variable in packages/golang/Makefile
mentions powerpc.

What would need to be done to get Go packages to compile for the APM82181?
