Just a small updater which should fetch the latest sha256sums from the
upstream site and check whether the current version is the latest one.
The output is in a JSON file in the same directory, which then will be
used by the Nix expressions to fetch the upstream files.

It's my understanding that Emacs runs the "structured-haskell-mode" binary
virtually every time you press a key in an Haskell buffer, and since
dynamically linked Haskell binaries take *much* longer to start up, switching
this particular package to statically linked libraries ought to result in a
performance boost.
These changes are needed to be able to run the system emulator (QEMU)
from Android Studio. In addition to the added dependencies,
$LD_LIBRARY_PATH had to be changed from --set to --prefix, so that libGL
is found (on NixOS).
The opam package manager relies on external solvers to determine package
management decisions it makes related to upgrades, new installations,
etc.
While, strictly speaking, an external solver is optional, aspcud is
highly recommended in documentation. Furthermore, even having a
relatively small number of packages installed quickly causes the limits
of the interal solver to be reached (before it times out).
Aspcud itself depends on two programs from the same suite: gringo, and
clasp.
On Darwin, Boost 1.55 (and thus Gringo) do not build, so we only support
Aspcud on non-Darwin platforms.
It's a long build and generally painful to split into smaller commits,
so I apologize for lumping many changes into one commit but this is far
easier.
There are still several outdated parts of the darwin stdenv but these
changes should bring us closer to the goal.
Fixes#18461
