Well, package-install shall do some book-keeping, which Emacs version
has been used for compiling a package. And when a new Emacs version
appears, it shall trigger a warning, or a recompilation, or whatever.

(I know there are traps for people like us, who change often the Emacs
version in order to check bugs)

Hmm, maybe I'll do it at least for Tramp. Keep a variable for the Emacs
version used for compilation, and react somehow, if another (major)
Emacs version is used.
