cmd/dist: enable build cache always GOCACHE=off is not a reliable signal of user intent. At startup the go command fills in an empty GOCACHE with the effective setting. If $HOME is set, then GOCACHE ends up somewhere in $HOME/.cache. But if $HOME is unset, then the go command sets GOCACHE=off explicitly. That environment is used for invoking "go tool dist". So if the machine has no $HOME, then go tool dist ends up with the cache disabled even though the user was not trying to disable the cache. This affects the linux-ppc64le builder, which appears to be unique among builders in not having $HOME set. So that builder is running with no build cache. Now that there is a cmd/go test that needs the cache to be on, the linux-ppc64le builder is failing. In the next release we intend to force the use of the build cache always. This CL is not doing that: it's only forcing the use of the build cache during all.bash, which won't affect the majority of our users (they run pre-build binary releases). If this is a problem we can roll it back and fix the linux-ppc64le builders some other way. While we're here, print a few more useful variables in 'go tool dist env' and sort the output.
