x/build/cmd/release: leave oldlink binary out of RC1 (if the beta doesn't uncover serious linker issues) #39509
Description
As part of https://golang.org/s/better-linker, we now build a binary called oldlink in our release of Go. While it may be useful to include in the beta, we should make a decision on whether this is included in the RC or final releases of Go 1.15, vs asking people to rebuild it on their own if necessary.
