cmd/dist: toolchain3 fails in external linking mode due to stale targets

[erifan]

What version of Go are you using (go version)?

$ go version
tip

What did you do?

$ GO_LDFLAGS="-linkmode=external" ./make.bash

What did you expect to see?

Successfully build go

What did you see instead?

$ GO_LDFLAGS="-linkmode=external" ./make.bash

Please fill out the complete issue template — what is the output of go env in your environment from a non-external build?

In addition, what toolchain and version are you using for the external linker? (Does this reproduce with both gcc and clang toolchains, or just one of the two, or just one specific version?)
