Yes, this is what the configure flags do. And, all other emacs packages
in Guix follow this convention. So, I thought it appropriate for notmuch
to do the same.

The make-autoloads phase generates autoloads for notmuch commands so
that the full elisp files are loaded only at the last moment when some
notmuch command is actually invoked. This reduces the emacs startup
time. Again, all emacs packages in Guix have autoloads.

Shall I push?
