[bug#40677] [PATCH V3 07/15] gnu: Add ffmpeg-jami.

Hello Jan,

Good job! Variables prefixed by '%' often denote parameters (see:
https://www.gnu.org/software/guile/manual/html_node/Parameters.html).

I guess something like:

--8<---------------cut here---------------start------------->8---
(define %fmpeg-linux-configure-flags
  '("--flag-1"
    "--flag-2"))
--8<---------------cut here---------------end--------------->8---

would be fine. But using "ffmpeg-linux-configure-flags" would also be
correct.

Thanks,

Mathieu
