* 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].

This fixes how GOARM is selected for arm platforms, based on support for
VFP/VFPv3 rather than CPU version.
Fixes#10967.

This adds support to compile host and target Go as position-independent
executables.
Host Go will have PIE enabled if Go supports PIE on the host platform.
Target Go will have PIE enabled if Go supports PIE on the target
platform and CONFIG_PKG_ASLR_PIE is selected.
Go 1.13 supports PIE for x86 and arm targets; mips support is in
progress[1].

This changes the formatting of environment variable unexports in
golang-values.mk to be more maintainable, and to document the sources of
variables.
There should be no change to the actual list of variables unexported.

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.

These Go library packages were added to support obfs4proxy. As
obfs4proxy was updated to allow dependency management by the Go
compiler, these packages no longer have any dependants.
This removes these packages from the feed.

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.
