IMO, the "no writable eln-cache" scenario should be solved by tweaking
native-comp-eln-load-path to include a writable directory.  That
writable directory could be temporary-file-directory, or it could be
anything else, but it should be specified by the caller/user, not
pulled out of our hat behind the scenes.
