A single commit to cmd/go reverts an optimization on plan9 because it was failing the plan9 builders, a reminder that the toolchain's build path is still tuned per platform.

cmd/go: disable early export on plan9 golang/go

by Michael Matloob

Michael Matloob landed a change that disables early export for cmd/go on plan9. The commit message is blunt about why: "It's breaking the plan9 builders." Only plan9 is affected; other platforms keep the existing behavior, and there is nothing to change in your own module or build setup.
