The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
quick-lint-js' build system supports cross compiling, but it's not
automatic.
Prior to quick-lint-js version 2.13, cross compiling with Nix works
because some build-time tools are optional. These build-time tools need
a compiler from buildPackages.stdenv. Version 2.13 made these build-time
tools required.
Refactor the quick-lint-js package to use quick-lint-js' cross
compilation support. This fixes cross compilation with Nix.
