Build libpizlo (Fil-C runtime library - GC + memory safety) Use the original Makefile - it knows which files to build

prctl's capability options returned ENOSYS, so systemd could start no service.

../patches/filc-runtime-prctl-caps.patch

Staging already has this fix; the official releases do not.

pkgs.lib.optionalsources.variant ≡ "release" ../patches/fil-c/runtime-exception-unwind.patch

zsys_brk reports the program break, so sbrk(0) works as it does natively.

../patches/filc-runtime-brk-query.patch

Proof of concept: zclosure_new_sealed (docs/sealed-closures.md).

pkgs.lib.optionalsources.variant ≡ "staging" ../patches/fil-c/sealed-closures.patch

zmark_shared: shared mappings whose pointers hold addresses only (docs/zmark-shared.md). Staging only; the pass half is in compiler/filc0.nix.

Under glibc, libpas includes filc/llvmjit/filc_llvm_jit_api.h, which is generated from LLVM's C API headers.
