Confirmed the issue.

I'm not sure where -mmacosx-version-min=10.11 came from. I think this is from Go 1.15 compiler, but is that true?

$ find . -name "*.go" | xargs grep "mmacosx-version-min"                                                                                                                                                                                      
./src/crypto/x509/root_cgo_darwin_amd64.go:#cgo CFLAGS: -mmacosx-version-min=10.11

My guess is that this should be omitted when ios build tag exists.

Change https://golang.org/cl/244777 mentions this issue: crypto/x509: do not specify -mmacosx-version-min on iOS

This issue does not happen with the latest Go, then the next version of Go 1.15 has already fixed this issue.

(Probably 72019cf fixed this?)

Go 1.15 rc1, which was released 30 minutes ago, did not cause this issue. Let me close this.

Thanks for investigating and confirming this is fixed, Hajime.
