Before this change, if you were cross compiling Nix, then the nix-manual subproject would never get built. In some situations, it makes sense to not build the nix-manual subproject when cross compiling. For example, if the build system is x86_64 and the host system is riscv64, then it makes sense to not build the manual. Building the manual requires executing certain build artifacts, and you can’t run x86_64 executables on riscv64 systems. That being said, there are some situations where it does make sense to build the nix-manual subproject when cross compiling. For example, if the build system is x86_64 and the host system is i686, then it doesn’t make sense to not build the manual. You can run i686 executables on x86_64 systems just fine. This change makes it so that the nix-manual subproject will sometimes get built when cross compiling. Specifically, the nix-manual subproject will get built as long as the doc-gen option is enabled and the build system is capable of running host binaries. --- The main motivation behind this change is to fix this Nixpkgs issue [1]. Building pkgs.nixStatic counts as cross compiling Nix, and pkgs.nixStatic is supposed to produce a man output. Building pkgs.nixStatic currently fails because it isn’t actually producing a man output. That issue will go away once this commit gets backported to Nix 2.28.x.
