Trying to redo the way I build my site so that it's simpler to maintain, and one
thing that was getting in my way was that ‘lessc’ isn't packaged for Guix. Sass
on the other hand is, so I've switched.
The initial generation of ‘build.mk’ can't use Eldev anymore, because Eldev
expects there to exist a file with proper package headers, which won't be true
until after ‘build.mk’, ‘Eldev’, and ‘publish.el’ have been generated.
