In https://go-review.googlesource.com/c/go/+/421879/13/api/next/46731.txt, we needed to list:

pkg runtime/cgo (darwin-amd64-cgo), type Incomplete struct #46731
pkg runtime/cgo (freebsd-386-cgo), type Incomplete struct #46731
pkg runtime/cgo (freebsd-amd64-cgo), type Incomplete struct #46731
pkg runtime/cgo (freebsd-arm-cgo), type Incomplete struct #46731
pkg runtime/cgo (linux-386-cgo), type Incomplete struct #46731
pkg runtime/cgo (linux-amd64-cgo), type Incomplete struct #46731
pkg runtime/cgo (linux-arm-cgo), type Incomplete struct #46731
pkg runtime/cgo (netbsd-386-cgo), type Incomplete struct #46731
pkg runtime/cgo (netbsd-amd64-cgo), type Incomplete struct #46731
pkg runtime/cgo (netbsd-arm-cgo), type Incomplete struct #46731
pkg runtime/cgo (netbsd-arm64-cgo), type Incomplete struct #46731
pkg runtime/cgo (openbsd-386-cgo), type Incomplete struct #46731
pkg runtime/cgo (openbsd-amd64-cgo), type Incomplete struct #46731
pkg runtime/cgo, type Incomplete struct #46731

in the api/next file. This is because if the file instead contains just the last line, cmd/api complains:

##### API check

+pkg runtime/cgo (darwin-amd64-cgo), type Incomplete struct

±pkg runtime/cgo, type Incomplete struct

But shouldn't the goos-goarch-cgo targets fall back to the context-free definition? Why isn't that working here?
