Subject: 🌭 plan9-kencc-linux: кросс-тулчейн Plan9 (cc/as/ld) + EFI-болванка
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- build_arch.sh / build_al.sh: сборка kencc-компиляторов, ассемблеров,
  линкеров всех арок (5/6/8/v/q/k) на Linux-хосте через plan9port.
- патчи под musl/gcc: sbrk->mmap, round/log2->p9*, Runemask, swcmp const,
  -fcommon, machcap/omachcap, /sys рантайм-файлы. Подробно в PATCHES.md.
- bin/: готовые 8c 6c 5c vc qc kc + 6a 6l (Linux/musl x86_64).
- efi/: болваночный bootx64.efi (PE32+) тем же тулчейном (6a+6c+6l+dd),
  референс — 9legacy nboot/efi; ESP-образ через mkesp.py.
