When trying to jump to the first step, DONE-STEPS ends-up being null, which
fails the matching condition.

* gnu/installer/steps.scm (skip-to-step): Split matching conditions to handle
the empty DONE-STEPS case properly.

In the long run, it would be good to move direnv across to the
go-build-system, and update the package, but these changes do succeed in
reducing the closure size a lot.

Thanks to Tanguy Le Carrour for raising this issue on guix-devel.

* gnu/packages/shellutils.scm (direnv)[arguments]: Include the
remove-go-references phase from the go-build-system.

This is the last bit fixing <https://bugs.gnu.org/35283>.

Previously, 'mformat' (used by 'grub-mkrescue') would pass uninitialized
bytes to write(2), leading to non-deterministic FAT image contents.
This patch fixes that.

Until now, the 'guix' package shipped in binary tarballs and system

Now all of them can potentially be built in parallel.
