Marking as runtime/compiler because one of the failures is in cmd/cgo/internal/testtls.

There is also a cmd/go failure due to

set CGO_ENABLED=1
go build -x runtime/cgo

unexpectedly succeeding when %PATH% is empty.

@qiulaidongfeng, could you run go test -v cmd/go -run=TestScript/cgo_stale_precompiled to reproduce it with more verbose logs, and file that as a separate cmd/go issue?
