Subject: [Buildroot] [Golang] Add support for a bootstrap binary

Hello,

Currently, on the supported systems, one way to build Go on the host
machine is to build it from a binary bootstrap toolchain because the
source bootstrap toolchain (Go 1.4) does not target some supported
architectures (ppc64le, aarch64...).

In practice, I would like to be able to build Go on a *aarch64*
machine. Then, cross-compiled Go packages to run them on an *arm*
machine.

  $GOHOSTARCH)
