Also:

  * Upstream Spack assumes that 'linux-headers' is
    always installed on the system, since it is a
    dependency of glibc. As 'openssl' requires it,
    make the dependency explicit. There are likely
    many more occurrences of this that should be
    reported and fixed upstream.

Commit 49431cc5 bumped
Python but did not delete the patch rendered obsolete.

See also: #828

Closes: #1104

Switching to a file-based (as opposed to patch-based)
configuration will be easier for us to maintain. Note
that '/opt/spack/etc/spack/config.yaml' will override
values in '/etc/spack/config.yaml'.

Also:

  * change upstream spack.git provider; fixes spack#8,
    which gives users immediate access to our patches
    if they wish to set up a separate Spack tree

Additional changes:

  * add 'linux-headers' to makedepends; required by openssl
    during clingo bootstrap

  * add .post-install file to inform admins about usage

  * ppc requires explicit -latomic; this patch fixes spack#6
    for both the initial clingo bootstrap and 'spack install clingo'

  * fix regression where all targets not supported by golang/rust
    could not be bootstrapped; this patch fixes spack#7

  * pmmx still requires the archspec patch; fixes #794

  * enable debug output during bootstrap build

  * disable buildcache by default (do not attempt to pull binaries)

  * fix package paths

  * Make dependencies explicit
    https://spack.readthedocs.io/en/latest/getting_started.html#system-prerequisites

  * Remove cached compiler preferences; this causes problems
    if e.g. 'ccache' is used ('/usr/local/bin/gcc') when built
    but the same path does not exist on the installed system.

  * Do not attempt to use the buildcache (search remote server
    for pre-built packages). We are the only musl-based distro
    currrently packaging Spack, and no such binaries exist yet.

Adds modules for most RTCs supported on arm64.  We also now build-in
RTC_EFI, which should grab most of the server-class boards.

It seems prudent to allow users to fetch files from remote servers in
the Base environment.

The new binutils version allows more options on aarch64, pmmx, and
x86_64.  Configure them so that native builders don't have `oldconfig`
output.

Fixes: #1091, #1092, #1094

Additionally, ensure shared libraries are versioned.

This fixes a regression from the autotools-based era
that was not carried into the CMake era.

This updates the outputs to 1.0-beta5.

* Set cap_sys_time on horizon-qt5 to allow setting the clock.
  (horizon#321)

* Move gfxdetect to graphical runlevel. (horizon#346)

* Change install scripts to local.d scripts.

* Add a local.d script to make dhcpcd setuid. (horizon#361)

* Make the Desktop Entry file a real file instead of a heredoc.

* Remove setuid bit from the shell script; we don't need this any more.

* Pull in our new LXQt theme for a better experience.

* Add XFCE subpackage.

* Set PATH correctly for horizon-run-qt5 so it can find mkfs.vfat and
  friends.

* Set the clock with chronyd if possible on boot, before the graphical
  environment starts.

* Use sudo for partitionmanger. (horizon#368)

Ref: #1081

Defines a base LXQt theme that is functional and appealing.

This supplies the fonts we want for all desktop environments.

Ref: horizon#353

This update brings some reliability fixes to i915/i965, nouveau, and
also radeonsi.  This is the most recent version of the 'amber' branch
which is the last version with support for these chipsets.

There is a way to co-install mesa-amber and mesa, but we will need to
work on that.  For now, we ship this for everyone.

The nouveau patch here is sent upstream and fixes context destroys.

This fixes all the stupid EFI bugs in Horizon.

Upstream: https://github.com/OpenRC/openrc/issues/238

Add more network drivers to the ppc64 config.  Requested by @djt.
