Luanti: LuaJIT's state allocated where it refuses it (2026-10-16/17)

Symptom. Debian has no ppc64 Luanti (its control lists only LuaJIT architectures; s390x builds 5.15.2 and passes the unit tests, a 2025 ppc64 attempt at 5.10.0 aborted in TestSAO). Our build started, but luaL_newstate() failed about 40% of the time, and with it the game.

Cause. Debian’s LuaJIT on ppc64 big-endian allocated its state between 2 and 4 GB, which LuaJIT itself then refuses: it checks that the state lies in the low 2 GB.

Fix. Our luajit’s 0001 (packages/patched/libs/luajit/, commit 331c539) makes ppc64 big-endian allocate in the low 2 GB. Luanti’s 330 unit tests pass with it. The library serves every consumer of LuaJIT on the image, not only Luanti. A second big-endian bug in the same port was the sound: Luanti decoded Ogg Vorbis in little-endian order, which played as noise (Luanti 0003, commit 7b5b968).
