The various pkgsXYZ top-level package sets did not pass localSystem / crossSystem to lower levels, so far. This change propagates original arguments to lower levels, which include the overrides made by an upper package sets. There is an extensive test-suite to test various combinations of package sets in pkgs/test/top-level. There are a few basic promises made: - Package sets must be idempotent. pkgsMusl.pkgsMusl === pkgsMusl. - Once pkgsCross is used any subsequent package sets should affect the **host platform** and not the build platform. Examples: - pkgsMusl.pkgsCross.aarch64-multiplatform is a cross compilation from musl to glibc/aarch64 - pkgsCross.aarch64-multiplatform.pkgsMusl is a cross compilation to musl/aarch64 - Modifications from an earlier layer should not be lost, unless explicitly overwritten. Examples: - pkgsStatic.pkgsMusl should still be static. - pkgsStatic.pkgsCross.gnu64 should be static, but with glibc instead of musl. Exceptions / TODOs: - pkgsExtraHardening is currently not idempotent, because it applies the same flags over and over again.
