This changes the default build cache directory from $(TOPDIR)/.go-build
to $(TMP_DIR)/go-build, so that the cache directory is ignored by git
and is removed by "make dirclean".
This does not move/remove a build cache directory in the previous
location; it will need to be removed manually.
Fixes https://github.com/openwrt/packages/issues/13675.

This also adds GO_PKG_INSTALL_BIN_PATH which determines the path where
binaries are installed by GoPackage/Package/Install/Bin (this was
previously hard-coded to /usr/bin).

In Go 1.15, the linker now defaults to internal linking mode for
-buildmode=pie on amd64 and arm64[1], however this results in go tool
binaries with the wrong dynamic linker/interpreter.
External linking is still used when PIE is enabled for other platforms,
whereas internal linking is used when PIE is not enabled.
This changes target Go to always use external linking, to fix PIE
binaries for amd64/arm64 and for consistency.

This adds a new Makefile variable, GO_PKG_TAGS, for Go packages. When
set, the value is passed as the parameter of the -tags option for 'go
install'.
This also updates syncthing to use this variable.

This evaluates the arguments passed to "go install" during Build/Compile
rather than when golang-package.mk is included.
This also changes build directory-related variables to be recursively
expanded, because PKG_BUILD_DIR depends on BUILD_VARIANT and so can
change during different runs of Build/Compile.

Because the first stage for building target Go is actually a host build,
the default platform options (GO386, GOARM, etc.) are detected from the
host. These values are written to a source file and kept when building
the second stage.
This modifies this source file to set the appropriate values for the
target platform, and reset values for other platforms to their
cross-compiling / most compatible defaults.

The moves the setting of arguments for "go install" out of the shell

The variable is a list of shell variables; the new name is more in-line

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.

The default bootstrap Go (Go 1.4) can only be compiled on a limited
number of platforms compared to newer versions of Go.
This adds a config option to use an external bootstrap Go, e.g.
installed through the build system's package manager or downloaded from
golang.org.

* 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_*

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].
