commit: https://git.buildroot.net/buildroot/commit/?id=ec50eb3e4226e69d11dffff8e509a981586dd81f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Add a new package 'go' which builds the host cross compiler and
libraries for the go programming language.
Signed-off-by: Geoff Levand <geoff at 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.]
