[PATCH 0/4] v2: Use emacs-minimal to build emacs packages.

[Alex Kost]

This is the updated patchset for adding emacs-minimal and using it to
build emacs packages.  Only PATCH 2 is new: I removed the mess I did
with native-inputs and used #:emacs keyword for auctex instead (thanks
to Federico and Ludovic for the comments!).  The rest patches are the
same as they were.

[PATCH 1/4] gnu: Add emacs-minimal.
[PATCH 2/4] build-system/emacs: Use 'emacs-minimal' by default.
[PATCH 3/4] gnu: Move emacs for building from inputs to native-inputs.
[PATCH 4/4] gnu: Use 'emacs-minimal' instead of 'emacs-no-x'.
