What did you do?

I use go tool dist list to get the architectures available for cross-compilation (CI workflow).

What did you expect to see?

The list of architectures available for cross-compilation. This worked fine in Go 1.20.x.

What did you see instead?

Our current thinking is that shipping go tool dist is excessive, but breaking scripts that rely on go tool dist list is also unfortunate. Perhaps we can allow cmd/go to impersonate dist when the command is go tool dist list and the dist tool isn't present.

Mentioning that there is a workaround that can be used with go1.21rc2:

~ $ go version
go version go1.21rc2 darwin/arm64
~ $ go tool dist list
go: no such tool "dist"
~ $ GOROOT=$(go env GOROOT) go run cmd/dist list          
aix/ppc64
android/386
android/amd64
android/arm
[...]

It is more verbose than just go tool dist list, and slightly slower since go builds the dist command on the fly. But that wouldn't be noticeable in the context of a CI job.

Also switch internal/platform to commit the generated code instead of
regenerating it in cmd/dist. Nothing in the generated code depends on
the target configuration, and committing the source file makes it
more amenable to searching and indexing (particularly on
https://cs.opensource.google/go/go).

For #60939.

It's viable to use go tool subcommand now that CL 505176 landed.
It's included in the recent Go 1.21 Release Candidate 3 release.
