All Go packages must depend on BR2_PACKAGE_HOST_GO_TARGET_ARCH_SUPPORTS,
which ensures that we do have a Go compiler available for that target.
BR2_PACKAGE_HOST_GO_TARGET_ARCH_SUPPORTS is currently restricted to the
availability of a full host Go compiler bootstrap. However, there are
architectures like AArch64 for which a full bootstrap is not supported.
Thus, currently, on an AArch64 host, we can't build Go packages (for
target or host), because we can't bootstrap a Go compiler.
However, note that a single Go compiler can generate code for all the
architectures supported by Go and for some host architectures, there are
pre-built toolchains available. When host-go-bin was added in commit
7b2a164b74 ("package/go/go-bin: new host-go provider"), the host
dependency was properly accounted for: It is already possible to build
host-go packages with go-bin. However, the fact that a Go compiler, in
addition to its native target, can also generate code for all supported
architectures, was missed at the time.
Thus, we can fix this problem by relaxing the condition under which
BR2_PACKAGE_HOST_GO_TARGET_ARCH_SUPPORTS is set to allowing go-bin
along with go-bootstrap. This allows a situation where the host can't
bootstrap, but for which there is a pre-built toolchain to build Go
packages for a supported target.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
