* Source vendoring is passed as a standalone attribute to `mkCargoDerivation`, meaning it does not automagically get spliced with the correct local/cross system inputs (i.e. what would happen if it was a `depsBuildBuild` entry) * To fix this we need to make sure that `vendorCargoDeps` and all of its transitive dependencies always use `runCommand` (and friends) from their `pkgsBuildBuild` equivalent. This should always be safe to do (even for cross-builds) since this amounts to building up a bunch of sources which will be read by the build system * Unfortunately I had to manually specify `pkgsBuildBuild.whatever` in multiple places as I could not get things to work by messing with the `callPackage` definition. Perhaps we should be using `makeScopeWithSplicing'` instead of `makeScope` when constructing the library, but I couldn't get it working (and I couldn't find any decent docs on how to use it online) so this will make do for the time being.
