Also begin to start work on cross compilation, though that will have to be finished later. The patches are based on the first version of https://reviews.llvm.org/D99484. It's very annoying to do the back-porting but the review has uncovered nothing super major so I'm fine sticking with what I've got. Beyond making the outputs work, I also strove to re-sync the packages, as they have been drifting pointlessly apart for some time. ---- Other misc notes, highly incomplete - lvm-config-native and llvm-config are put in `dev` because they are tools just for build time. - Clang no longer has an lld dep. That was introduced in db29857eb391ed002046090851a44c452b80bdbd, but if clang needs help finding lld when it is used we should just pass it flags / put in the resource dir. Providing it at build time increases critical path length for no good reason. ---- A note on `nativeCC`: `stdenv` takes tools from the previous stage, so: 1. `pkgsBuildBuild`: `(?1, x, x)` 2. `pkgsBuildBuild.stdenv.cc`: `(?0, ?1, x)` while: 1. `pkgsBuildBuild`: `(?1, x, x)` 2. `pkgsBuildBuild.targetPackages`: `(x, x, ?2)` 3. `pkgsBuildBuild.targetPackages.stdenv.cc`: `(?1, x, x)`
