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.

Add a new package 'go' which builds the host cross compiler and
libraries for the go programming language.

[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.]
