Previously the script would contain an empty `if` block (which is invalid
syntax) if both `data.activationDelay == null` and `data.postRun == ""`. Fix
this by adding a no-op `true`.
Previously we indirectly suggested that the user use
services.printing.extraConf to set this, but this doesn't work with the
default merge ordering. Fix this by making it an independent option.
Fixes#39611.
Otherwise the build fails with the perplexing error
make: *** No rule to make target 'cmd-list.made', needed by 'doc.dep'. Stop.
make: Leaving directory '/tmp/nix-build-git-2.16.3.drv-0/git-2.16.3/Documentation'
on NixOS (but not on Debian, where it succeeds, presumably since it picks up the
system perl).
This is a commonly-used package for spatial indexing.
Strangely enough, the tests are broken due to memory unsafety that I was unable
to reproduce under Debian. For instance, when run with Python 3.6 valgrind
reports,

It turns out that the build system does not support building both the
command-line tool and the shared library at the same time. Consequently
the ngspice derivation has not provided the command-line tools since the
shared library was enabled in #31166.
Cabal2nix expects a --compiler flag that contains a Cabal Compiler description.
We used to use the compiler's derivation name for this, but this breaks when
cross-compiling due to the target suffix. Instead we add an explicit
haskellCompilerName attribute to Haskell compiler derivations.
Previously configureFlags was defined as one giant interpolated string.
Here we refactor this definition to instead use the usual stdenv string
combinators. This seems more in-line with the average nixpkgs expression
and it seems a bit more natural to things of these as lists of flags
rather than monolithic strings.
