Instead of "CC=gcc", you should use

                 (string-append "CC=" ,(cc-for-target))

for cross-compilation.

Here, I think it is preferable to use

          (string-append "PREFIX=" (assoc-ref %outputs "out"))

Typo: ";no install target"

It would be nice to expound Dwm, e.g.,

  "Dynamic window manager for Wayland"

This should be a complete sentence, e.g.,

  Dwl is a compact, hackable...

I suggest rewrite so it doesn't include a list. For example:

  Like dwm, dwl is easy to understand and hack on, due to a limited
  size and a few external dependencies.  It is configurable via @file{config.h}.

Could you send an updated patch?
