No, I don't think so. I think you should have these autoloads in the
Lisp part of your package.
So I suggest to review your definition of the package that package.el
uses to decide which files to scan for autoloads, and perhaps change
it to not imply that _mymod.so should be scanned.
Caveat: I have never prepared any package using the package.el
infrastructure, so I could be wrong in what I write above. Or it
could be a bug in package.el, in which case I suggest to report it,
including all the details, using "M-x report-emacs-bug RET".
Thanks.
