How to clean cache for 'go tool dist test'

[Xiangdong JI]

Hi,

I'm trying to run 'go tool dist test' after the binary has been built successfully, while always get a cached result,

running "go clean -i -r -testcache <pkg>" and "go clean -cache" in prior doesn't help, can anyone please help here? 

Thanks.

$ go tool dist test -run=go_test:crypto/

# go tool dist test -run=^go_test:crypto/aes$

Why are you running `go tool dist test` and not just `go test`?

Do you have GOARCH or GOOS set?

I always got a timeout when running all.bash (synced to the latest commit cbd421f75b0770c3534d1b641e7770bf1878004f),

it's not reproducible with 'go test -run=. crypto/tls', no GOARCH and GOOS were set previously. Thanks.

Update: I cannot reproduce the time-out issue any longer. Thanks all.

Still curious to know if there is any way to clean the cache, there used to be GOCACHE=off, but seems that it's not supported now.
