If one explores Nixpkgs, they will see derivations with names like `gccCross`. Such `*Cross` derivations is a holdover from before we properly distinguished between the host and target platforms—the derivation with “Cross” in the name covered the `build = host != target` case, while the other covered the `host = target`, with build platform the same or not based on whether one was using its `.nativeDrv` or `.crossDrv`. This ugliness will disappear soon.

# The solution is to splice the package sets together as we do below, so every
# `callPackage`d expression in fact gets both versions. Each# derivation (and
# each derivation's outputs) consists of the run-time version, augmented with a
# `nativeDrv` field for the build-time version, and `crossDrv` field for the
# `__spliced.buildHost` field for the build-time version, and `__spliced.hostTarget` field for the
# run-time version.

# We could have used any names we want for the disambiguated versions, but
# `crossDrv` and `nativeDrv` were somewhat similarly used for the old
# cross-compiling infrastructure. The names are mostly invisible as
# `mkDerivation` knows how to pull out the right ones for `buildDepends` and
# friends, but a few packages use them directly, so it seemed efficient (to
# @Ericson2314) to reuse those names, at least initially, to minimize breakage.
#
# For performance reasons, rather than uniformally splice in all cases, we only
# do so when `pkgs` and `buildPackages` are distinct. The `actuallySplice`
# parameter there the boolean value of that equality check.
