nx_nxmake.nx

nxmake.nx -- sovereign build driver (replaces GNU make). Scope claim: GNU make is Turing-complete and huge. We don't need most of it. The typical Nishi build is: list of inputs -> one or more command invocations -> an output file. Make's real differentiator is MTIME-based staleness checking; we replicate that with fs.nx's fstat. Replaces on the Nishi build path: make / gmake / bmake — any POSIX make File format: plain-text stanzas in "nx.build": target: kernel.elf inputs: boot.S trap.S src/sched_bootstrap.S nishi-kernel.s cmd: ./nxld --base 0x80000000 -o kernel.elf <inputs> target: nishi-kernel.s inputs: src/kmain.nx src/uart.nx ... cmd: ./nxc2 --target asm --opt src/kmain.nx > $@ Comments: lines starting with '#'. Blank lines separate stanzas. Subprocess-exec is intentionally absent from this seed. Windows host (CreateProcessA) and Linux host (clone+execve) diverge at the syscall layer and we don't have a portable abstraction yet. Instead nxmake emits a build plan -- an ordered list of commands and their staleness verdicts -- that a thin shim script runs. This is honest: nxmake owns the dependency reasoning, the shim owns the syscall specifics. Decoupled sovereignty.
