go: new host package
Add a new package 'go' which builds the host cross compiler and libraries for the go programming language. Signed-off-by: Geoff Levand <geoff@infradead.org> [Thomas: - Put the computation of GO_GOARM inside the ifeq ($(BR2_arm),y) condition rather than duplicating this condition. - Remove the GO_GOARCH=unknown case, since there is no way to fall in this case as only supported architectures can use host-go. - Remove the GO_GOARM=unknown case, since we are sure that only ARMv5/6/7 will use host-go. - Rename HOST_GO_FINAL to HOST_GO_ROOT, since it's really the "root" of the Go installation. - Remove visible Config.in.host option.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
