Hi,
This patch adds an emacs package for flymake[0]. Flymake is both
distributed as a built-in package and also as part of GNU Elpa. The version
in GNU Elpa has more frequente releases. Having it as a separate package
allows guix users to use the latest stable release.

[0]: https://elpa.gnu.org/packages/flymake.html

Cheers
