commit: https://git.buildroot.net/buildroot/commit/?id=f383d667e9ce89c1220dea22b920b31f7ec8c6d8
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.02.x

This patch fixes a bug with the BR2_TOOLCHAIN_HAS_THREADS variable
handling which causes CGO_ENABLED to be always 0.

Furthermore, it fixes the cross compilation options for the go
compiler: setting CGO_ENABLED should be done only for the target
compiler not the host one.
