Bumping Go to 1.8.3 from 1.7.
Go 1.8 comes with significant performance improvements, particularly
around ARM: "CPU time required by our benchmark programs was reduced by
20-30% on 32-bit ARM systems."

On Darwin, user's trust preferences for root certificates were not honored.
If the user had a root certificate loaded in their Keychain that was
explicitly not trusted, a Go program would still verify a connection using
that root certificate. This is addressed by https://golang.org/cl/33721,
tracked in https://golang.org/issue/18141. Thanks to Xy Ziemba for
identifying and reporting this issue.
The net/http package's Request.ParseMultipartForm method starts writing to
temporary files once the request body size surpasses the given "maxMemory"
limit. It was possible for an attacker to generate a multipart request
crafted such that the server ran out of file descriptors. This is addressed
by https://golang.org/cl/30410, tracked in https://golang.org/issue/17965.
Thanks to Simon Rawet for the report.

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.

The go compiler's cgo support uses threads. If BR2_TOOLCHAIN_HAS_THREADS is
set, build in cgo support for any go programs that may need it. Note that
any target package needing cgo support must include
'depends on BR2_TOOLCHAIN_HAS_THREADS' in its config file.
Fixes build errors like these:
error: #warning requested reentrant code

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.

[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.]
