As mentioned in the documentation for `byte-recompile-directory`, it only
recompiles `.el` files if a) there is a corresponding `.elc` file and b) that
`.elc` file is older than the `.el` file. I assume either or both conditions
aren't met. If the second condition is met, simply using `touch` on the source
files should do the trick.

If you use `package.el`, you should be able to reinstall all your packages using
`package-install-selected-packages`.
