I think this issue can not be reproduced with emacs -Q, because in this
case Elpa packages are not added to load-path. With emacs -Q, flymake
will rightfully complain "No such file or directory", when you `(require
'any-elpa-package)`

However, during the normal Emacs session, all Elpa packages are on the
load-path, but flymake complains as if they were not.

For me the following reproduces the issue:
1. Start Emacs
2. Switch to scratch buffer
3. Enable flymake: M-x flymake-mode
4. Type:

    (require 'subr-x)

  Observe that flymake does not complain

5. Now load anything from Elpa:

    (require 'compat)

  Observe that flymake starts complaining, even though compat is on
  load-path and the expression above can be successfully evaluated.
