Switch all program and library Makefiles from host g++ (or the bare-metal x86_64-elf compiler) to x86_64-montauk-g++/gcc and drop the flags the target now owns: -nostdinc + kernel freestanding -isystem paths, -m64/-march, -fno-PIC, -mno-red-zone, -mcmodel=small, -static, -Wl,-m,elf_x86_64, -z max-page-size, --build-id=none. Deliberate policy flags stay (-ffreestanding, per-app SSE, -nostdlib + link.ld). Program builds now require the montauk toolchain and fail with a pointer to build-montauk-toolchain.sh; lib/ and libs/ keep the host fallback since the toolchain script bootstraps libc through it. Userspace is also now pinned to the cross GCC instead of drifting with the distro compiler. Co-Authored-By: Claude Fable 5 <[email protected]>
