cmd/go, cmd/link: support failure to create _cgo_import.go For a package that uses cgo, the file _cgo_import.go is created to record information required for internal linking: the non-Go dynamic symbols and libraries that the package depends on. Generating this information sometimes fails, because it can require recreating all the dependencies of all transitively imported packages. And the information is rarely needed, since by default we use external linking when there are packages outside of the standard library that use cgo. With this CL, if generating _cgo_import.go fails, we don't report an error. Instead, we mark the package as requiring external linking, by adding an empty file named "dynimportfail" into the generated archive. If the linker sees a file with that name, it rejects an attempt to use internal linking.
