With this you can add:
$(eval $(host-golang-package))
to a package .mk file to build for host.

The hidden Config.in option BR2_PACKAGE_HOST_GO_ARCH_SUPPORTS name is
not very clear as to whether it says whether Go is available for the
target architecture or the host architecture.
Until now, this was fine since there was support for host Go
packages. But as we are about to introduce support for building host
Go packages, we need to clarify the meaning of
BR2_PACKAGE_HOST_GO_ARCH_SUPPORTS. Since it says whether the target
architecture has support for Go or not, we rename it to
BR2_PACKAGE_HOST_GO_TARGET_ARCH_SUPPORTS.
And since BR2_PACKAGE_HOST_GO_CGO_LINKING_SUPPORTS is tightly related,
we rename it to BR2_PACKAGE_HOST_GO_TARGET_CGO_LINKING_SUPPORTS.

[Thomas: entirely rewrite commit log]

go-bootstrap is a host package that builds a first stage Go compiler,
later used to build the final Go compiler. However, this first stage
compiler only supports building on x86, x86-64 and arm as host
architectures, so we need to add the relevant architecture
dependencies to avoid having go-bootstrap built on other unsupported
platforms.
We do this by introducing BR2_PACKAGE_HOST_GO_BOOTSTRAP_ARCH_SUPPORTS
in a new package/go-bootstrap/Config.in.host file. This option is then
used by BR2_PACKAGE_HOST_GO_ARCH_SUPPORTS to make sure we can't enable
Go packages when the host architecture doesn't allow building the Go
compiler.

When built statically, runc try to link against Scrt1.o which is not
provided by uClibc ARM toolchain for static build only.
[...]arm-buildroot-linux-uclibcgnueabi/bin/ld: cannot find Scrt1.o: No such file or directory
collect2: error: ld returned 1 exit status
On ARM, Go forces the use of -pie, for some reason:
pie := (goarch == "arm" && goos == "linux") || goos == "android"
if pie { // we need to use -pie for Linux/ARM to get accurate imported sym
cgoLDFLAGS = append(cgoLDFLAGS, "-pie")
}
For this reason, add a dependency on BR2_TOOLCHAIN_SUPPORTS_PIE for ARM
CPUs to disable Go for such toolchains.
While at it, rewrap Go dependencies.

[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.]
