λpkgs, sources?, devLlvm?

pkgs
sources	default import./lib/sources.nix inherit pkgs;
When true, the final compiler wrapper runs the clang binary from an out-of-Nix LLVM build directory named by $FILC_DEV_LLVM at run time. Runtime libraries (libpizlo, glibc, libc++) still come from the pinned Nix-built compiler, so only the compiler itself is swapped.
devLlvm	default false
