Add go language support

Hi,

This series add support for the go programming language. I tested the build of the included flannel package on i386, powerpc64, arm (32 bit) and arm64. I did runtime testing of the generated flannel binary on arm64.

Patch 1 adds a host only bootstrap compiler needed to build the latest go versions. The host and target support can be build independently, but either of the two need this bootstrap package.

Patch 2 adds support for a host cross compiler, libraries and tools.

Patch 3 adds support for a native compiler, libraries and tools for the target.

Patch 4 add a go language package flannel that can be used to test the go compiler.

Please consider for merege.
