[Janneke Nieuwenhuizen <janneke@gnu.org>]

XXX TODO:

   v Boot a 64bit hurd, and
   v Guix shell --bootstrap -D -e '(@@ (gnu packages commencement) gnu-make-boot0)'
   v Guix build -e '(@@ (gnu packages commencement) gnu-make-boot0)'
   o Guix build hello,
   o Guix shell --bootstrap -D guix,
   o Push the commit below,
   o Re-check the bootstrap-tarballs build/hash,
   o Update this commit message with new commit hash,
   o Push it with remainder of hurd-team branch,
   o Update blog post draft,
   o Release blog post!

On commit:
    610e996dcc82ab7819e9c19d81fdc78b7a9c822c

Producing:
    /gnu/store/7n1vcnzgad4cppzcmd7vnadsggrfm9as-bootstrap-tarballs-0/

With guix hash -r:
    0m66rvp5728c12xab5042gd4v0l1df0821l68brscrc5qr08imsj

* gnu/packages/bootstrap.scm (%bootstrap-executables): Add entries for
x86_64-gnu.
(%bootstrap-guile-hash, %bootstrap-coreutils&co, %bootstrap-binutils,
%bootstrap-glibc, %bootstrap-gcc): Add entry for x86_64-gnu.
* guix/packages.scm (%supported-systems, %hurd-systems): Add x86_64-gnu.
(%cuirass-supported-systems): Remove x86_64-gnu.
* guix/utils.scm (target-64bit?): Add x86_64-gnu.
* m4/guix.m4: Add x86_64-gnu as a supported system.
