Fix typo.

Revert "gnu: emacs-org: Update to 9.2.4."

This reverts commit 348753349222206809f0b1f7d4ce5fbed43290f0.

The structure of the tarball is different when obtained from
"https://orgmode.org" and emacs-build-system no longer apply.  Therefore, the
package will not build.

Org has not been updated in ELPA to its latest version (9.2.4); this was
reported upstream.

    -s armhf-linux

on an x86_64-linux machine wouldn't have the desired effect
because (%current-system) would return "x86_64-linux" when 'same-arch?'
was evaluated.  This fixes that.

* gnu/packages/bootloaders.scm (make-u-boot-package)[same-arch?]: Turn
into a thunk so that (%current-system) is evaluated in the right

lint: Separate checkers by dependence on the internet.

I think there are a couple of potential uses for this. It's somewhat a
separation in to what checkers are just checking the contents of the
repository (line length for example), and other checkers which are bringing in
external information which could change.

I'm thinking particularly, about treating network dependent checkers
differently when automatically running them, but this commit also adds a
--no-network flag to guix lint, which selects the checkers that don't access
the network, which could be useful if no network access is available.

* guix/lint.scm (%checkers): Rename to %all-checkers.
(%local-checkers, %network-dependent-checkers): New variables.
* guix/scripts/lint.scm (run-checkers): Make the checkers argument mandatory.

(guix-lint): Adjust indentation, and update how the checkers are handled.

lint: Move the linting code to a different module.

To try and move towards making programatic access to the linting code easier,
this commit separates out the linting script, from the linting functionality
that it uses.

* guix/scripts/lint.scm (emit-warnings): Alter to to not use match-lambda, as
<lint-warning> isn't accessible.

loading the data in to a database, as you can work with the <lint-warning>

Revert "guix: node-build-system: Use guile-json instead of a custom parser."

The effect of this change was to import the (json parser) from the host
side into the build side. The solution here would be to do the equivalent
of ‘with-extensions’ for gexps. Since we don't use gexps for build
systems just yet, revert this for now.

This reverts commit 8eb0ba532ebbebef23180e666e0607ea735f9c1a.
