The moves the setting of arguments for "go install" out of the shell
script in GoPackage/Build/Compile and into make.
This also adds the -buildid link flag for reproducible builds.

The variable is a list of shell variables; the new name is more in-line
with other parts the build system (CONFIGURE_VARS, MAKE_VARS, etc.).
GoPackage/Environment is kept (for now) in case other feeds are using
it.

Since RSTRIP is defined in rules.mk as a recursively expanded variable,
there is no need to define it again after setting STRIP in
golang-package.mk.
This also adds a note to the comment for GO_PKG_LDFLAGS to say that -s
and -w flags are not necessary.

* Move more environment variables into GoPackage/Environment
* Split GoPackage/Environment into target and build sections
* Do not set GOROOT_FINAL for Go packages (setting it should only affect
the Go compiler and not Go packages)
* Set CGO_LDFLAGS to $(TARGET_LDFLAGS)
* Move GO_TARGET_* variables from golang-values.mk, and GO_VERSION_*
variables from golang-version.mk, into golang/Makefile
This also updates runc, containerd, and docker-ce to reflect the changes
in GoPackage/Environment.

* Set GOENV=off when building Go compiler and packages, to ignore user's
environment configuration file
* Set GOCACHE when building host Go
* Unset GOTMPDIR, to use the buildroot temp directory instead of temp
directories in build_dir

The ASLR PIE option was changed to a tristate option
(openwrt/openwrt@19cbac7d264dfca1f75849de64beb98830fbb1e4). This updates
the Go compiler package and golang-package.mk to account for this
change.
This also adds warning messages for when the user has selected PIE but
Go does not have PIE support for the chosen target.

This adds support to compile position-independent executables for
packages that use golang-package.mk.
Go packages will have PIE enabled if:
* Go supports PIE on the target platform;
* CONFIG_PKG_ASLR_PIE is selected; and
* PKG_ASLR_PIE (for the package) is not set to 0
Go 1.13 supports PIE for x86 and arm targets; mips support is in
progress[1].

go invokes the external linker by calling gcc, so -zxxx options in
TARGET_LDFLAGS (in golang-package.mk) need to be formatted as -Wl,z,xxx.

go build/install supports multiple -ldflags arguments, but they are not
combined; for each package, the latest match on the command line is
used.[1]
Previously, the main executable would not be affected by the default
ldflags if GO_PKG_LDFLAGS or GO_PKG_LDFLAGS_X were set. (The default
ldflags instructs go to use the external linker.)
This fixes golang-package.mk so that the default ldflags take effect in
all cases.

Go 1.13 added a new -trimpath option to the "go build" command[1] that
removes system paths from compiled executables. This replaces the
previous -trimpath flags.
There are still system paths in the compiled executable (for crti.o and
crtn.o, when cross-compiling); these appear to be stripped during the
packaging process.

This adds several variables for Go package Makefiles:
* GO_PKG_GCFLAGS - go tool compile arguments
* GO_PKG_LDFLAGS - go tool link arguments
* GO_PKG_LDFLAGS_X - go tool link -X definitions
Settings these will add the corresponding flags to the go install
command line. (Other command line arguments can still be added by
passing them as the first argument to GoPackage/Build/Compile.)
This also adds Go's runtime environment variables (GOGC, GOMAXPROCS,
GOTRACEBACK) to the unexport list.

go 1.11 added modules, which are cached locally. The go developers have
decided to make this cache read-only (golang/go#27455), which causes
problems with package clean / autoremove (#7635).
This adds a call to clear this cache right after building, as currently
there is no easy way to hook into autoremove (it may be possible to hook
into package clean).
This also adds whitespace (blank lines) to certain places in make
output, to aid debugging.

From golang.org:
The Go programming language is an open source project to make
programmers more productive.
This commit consists of two "parts":
* golang/host: Main Go compiler for host (installed to
STAGING_DIR_HOST/lib/go-cross), used to cross-compile Go programs to
be packaged.
* golang (and golang-src/golang-doc): Main Go compiler for on-target
development. These packages are quite large, but I would expect only
developers to install these.
