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>

package/go: fix building host go toolchain when target isn't supported The go toolchain can cross-compile by default. So most of the time, building a toolchain that supports a target, allows us to also build go binaries for the host. This is how support for host go packages was added: we use the same toolchain that was initially built only for target. But we might want to build a go binary for the host, when compiling a target for which go isn't supported. Then, building host-go will fail: by default, we build go for a specific target, and give the toolchain bootstrap scripts the cross compiler we'll use. This change modifies this behaviour: we only assume the go toolchain is cross-capable if we know the current target is supported. Otherwise this is a simple host go tool. We don't need to set any of the options needed for cross-compilation in that case. Thus, only set all the target-specific go options under a condition that the target arch is supported. The only option we still set is HOST_GO_CGO_ENABLED, and we always set it to enabled. It was also considered to create a separate package to build the go-for-host compiler which would be used for host-go-packages, but that would lead to a lot of duplication and is completely unnecessary.

package/go: implement go modules integration The Go compiler needs to know the "import path" to the root of package source repositories. Previously, this was done by creating a fake _gopath in the build directory and symlinking the package source into that path. Go has deprecated the GOPATH mechanism in favor of a new approach - Modules - which specifies the root import path (and dependencies) in a "go.mod" file. This commit moves Buildroot to use the new go.mod approach, which requires: - Passing GO111MODULE=on when building host or target Go packages. - Passing GOPROXY=off and -mod=vendor to prevent the Go module system from downloading by itself sources from the Internet. We currently only support Go packages that have all their dependencies in their source tree in "vendor" directories. - Specifying a <pkg>_GOMOD variable, which is used both to create a minimal go.mod file in the package source tree if it exists, and to invoke the right build targets. Indeed, all elements in <pkg>_BUILD_TARGETS are now relative to <pkg>_GOMOD.

package/go: fix cross-compilation settings This patch fixes a bug with the BR2_TOOLCHAIN_HAS_THREADS variable handling which causes CGO_ENABLED to be always 0.

package/go: fix building host go toolchain when target isn't supported The go toolchain can cross-compile by default. So most of the time, building a toolchain that supports a target, allows us to also build go binaries for the host. This is how support for host go packages was added: we use the same toolchain that was initially built only for target. But we might want to build a go binary for the host, when compiling a target for which go isn't supported. Then, building host-go will fail: by default, we build go for a specific target, and give the toolchain bootstrap scripts the cross compiler we'll use. This change modifies this behaviour: we only assume the go toolchain is cross-capable if we know the current target is supported. Otherwise this is a simple host go tool. We don't need to set any of the options needed for cross-compilation in that case. Thus, only set all the target-specific go options under a condition that the target arch is supported. The only option we still set is HOST_GO_CGO_ENABLED, and we always set it to enabled. It was also considered to create a separate package to build the go-for-host compiler which would be used for host-go-packages, but that would lead to a lot of duplication and is completely unnecessary.

# The go build system is not compatible with ccache, so use
package/go: Build host tools with host CC The go build system doesn't have the notion of cross compiling, but just the notion of architecture. When the host and target architectures are different it expects to be given a target cross compiler in CC_FOR_TARGET. When the architectures are the same it will use CC_FOR_TARGET for both host and target compilation. To work around this limitation build and install a set of compiler and tool binaries built with CC_FOR_TARGET set to the host compiler. Also, the go build system is not compatible with ccache, so use HOSTCC_NOCCACHE. See https://github.com/golang/go/issues/11685.

go: explicitly disable modules to avoid unintended network lookup Go "modules" refers to the dependency fetching, verification (hashing), and version control system built into Go as of 1.11. It is not desirable to have Go modules enabled in Buildroot in the normal case, as Buildroot manages downloading the sources, and third party dependency managers are typically not used. In the absence of the GO111MODULE environment variable, the Go compiler will correctly compile using the "vendor" version of dependencies downloaded by Buildroot during the compilation process for Go-based packages. However, if the user sets the GO111MODULE=on environment variable, the Go compiler will download the Go dependencies for Buildroot packages, using the modules system. This is potentially unintended behavior from user environment variables. This commit sets the GO111MODULE=off variable in the Go target and host compilation environments, disabling Go modules support for Buildroot mainline packages.
