Michael Marineau 0f19f5ae13 go: disable arm64-extras flag, currently broken
For some reason the arm64 build (intended only for generating a
pre-built std library) is leaking into the amd64 build, leaving the
installed `go` binary with the arm64 defaults compiled in.

Until this is resolved disable building the arm64 std library.
