This enables native-compilation and provides precompiled elisp files
for emacs-x11 and emacs-gtk3. The plain console emacs stays without
support for native compilation to keep it lean, as native-compilation
pulls in libgccjit (27MB) and gcc (172MB + deps)
as well as emacs-common-eln (15MB).
On slow machines, native compilation can be disabled by setting
(setq comp-deferred-compilation nil)
in your .emacs.
