Andrea, does anything similar to subr-native-comp-unit exists for
other types of symbols accepted by symbol-file: defvar and defface?

If not, then the only way to produce the same information for them
would be to generate the base name of the .eln file with
comp-el-to-eln-rel-filename, and then look for that file along
native-comp-eln-load-path, right?
