Neat!

I failed to see any connection to engineering and moved this to 
efi.scm.

Don't forget to add or update your copyright line.

I added a newline after ‘source’ to give this 81-character line 
some breathing room.

URLs, snippets, ... can grow wide and a few columns can save a 
pointless string-append or newlines.

This can be done with the

  (file-name (git-file-name name version))

helper.

Not a comment on your patch, but I added a 
‘support-cross-compilation’ phase here that replaces the 
Makefile's hard-coded ‘gcc’ so you can inspect EFI binaries on 
your cross-compiled ARM box.

> (assoc-ref %outputs "out")))))

The other way 'round: set $prefix (or the BSD variant $PREFIX) to 
the destination, and never set DESTDIR unless you're working 
around a bug in a broken build system.

DESTDIR is for distributions/builds using a temporary ‘staging’ 
destination directory.  Guix doesn't.

Slash empty ‘x can y’ (or ‘x allows the user to y’) filler with 
gleeful prejudice.

Pushed with these changes as 
373f808df229c12101301b766bd1810836b98481.

Thanks!
