Subject: Add golang-cross

This package is derived from meta-golang:
https://github.com/digitallumens/meta-golang.git
commit 3fa6c8af6b4762de2f4e6740e327a5a71c29e6e1

In the meta-golang version, golang depends on a gcc-cross that causes
conflicts with our toolchain. So the golang-cross recipe was extracted
and then the following changes were made to work in wrlinux:

- our TARGET_ARCH is x86-64, golang-cross wants amd64

- in the former recipe, compile fails because it can't find header files
  and libraries because --sysroot is dropped. So I redefined the target
  cc and target cxx as cc and cxx at the start of the compile rule since
  cc gets redefined in there somewhere.
