Keith Randall ca3749230b cmd/compile: allow bodyless function if it is linkname'd ... In assembly free packages (aka "complete" or "pure go"), allow bodyless functions if they are linkname'd to something else. Presumably the thing the function is linkname'd to has a definition. If not, the linker will complain. And linkname is unsafe, so we expect users to know what they are doing. Note this handles only one direction, where the linkname directive is in the local package. If the linkname directive is in the remote package, this CL won't help. (See os/signal/sig.s for an example.)
