282130a made make_release.build_sources take the release's profiles and left the call in make_release_linux.py with
one argument, so the Linux release stopped with a TypeError. The Linux setup compiles without a profile, so it passes
none.

-march=x86-64-v3 kept the port and the installer to CPUs with AVX2 and FMA. --cpu v2 compiles the generated code and the runtime for SSE4.2 instead. Without FMA3 the FP lowering calls fma/fmaf, so runtime/fma.c provides correctly rounded ones (musl, MIT) that honour MXCSR's rounding mode, FTZ and DAZ; the UCRT's software fallback rounds incorrectly by up to half an ulp. simd.h's fast paths keep their assumptions.
The installer's host check asks for x86-64-v2 and selects libtotkrt.a or libtotkrt-v2.a; both release scripts build and ship the pair. The differential tests compile fma.c as well, so a --cflags=-march=x86-64-v2 run tests it.
Tested on an i7-3770K (no AVX2, FMA or BMI) with an RTX 3060 Ti, game 1.4.3: the installer ran end to end, --selftest passed and play holds 40-60 fps at 1080p. fma and fmaf matched 152,288 exact vectors over two seeds, including ties, subnormals and every rounding mode, FTZ and DAZ combination. The v3 build is unchanged: fma.c is an empty translation unit there.
Shader preparation reads MacNativeGames' whole shader list history,
release downloads resume from a .part file, appimagetool and the type-2
runtime come from release tags, and the preparation summary counts the
vertex and fragment variants it skips with the graphics pipeline library
off.
The gettid cache in runtime/platform/linux.c conflicted with the same fix
already on dev (8dd7e20, #236); dev's version is kept.

A Steam Deck tester had 1.2 GB free in /home, where the setup put its 1.3 GB of generated C and objects
(~/.cache/totk-setup) and RADV its shader cache (up to 1 GB, about 35 MB a minute at the title screen), while the game
goes to the SD card. The setup's temp is now .setup-temp in the install folder (--temp changes it; the empty-folder
check leaves it out), and totk points MESA_SHADER_CACHE_DIR at mesa-cache beside itself unless it is set. A scan of
every ELF file in the release folder showed the bundled LLVM and the cryptography wheel need glibc 2.34, not the 2.31
the docs gave: make_release_linux.py now checks that floor (check_glibc), the setup's check stops below it
(check.glibc_old) instead of failing on a compiler that cannot start, and the docs give both floors. The Linux notes
also record the testers' results, that the Deck has the host-import extension too, and its software ASTC decoding.
make_release.py and make_release_linux.py built the runtime library and the --prove build from generated/v121 alone.
The library reads only what both versions' layout.h share (MOD_COUNT, MOD_MAIN_BASE), so both scripts now take
generated/v121, else generated/v143, pass its --version, and name extract.py and gen.py when neither exists.
tools/make_release_linux.py assembles the Linux release folder and packs it with the static type-2 AppImage runtime:
python-build-standalone 3.14 with tkinter, LLVM 23.1.4 (clang, lld, llvm-ar) and the part of the Steam Runtime 3 sniper
SDK sysroot a game build reads, so the game, hostcheck, hactool and the translator need no newer glibc than 2.31 and run
on SteamOS. The game it builds needs only glibc, the system's Vulkan loader and the libSDL3.so.0 beside it; Opus, libvpx,
zstd and libstdc++ are linked in. --prove builds generated/v121 with the folder alone and runs the probes.
The installer runs on Linux: release and dev layouts, temp under the XDG cache (the AppImage mount is read-only), cancel
through the CLI's process group, language from LANG, xdg-open and a PNG icon, texts that name the right executable, and a
warning on kernels older than 6.7. hostcheck reads x86-64-v3 from CPUID, since clang's __builtin_cpu_supports reads it
from libgcc, which before GCC 12 has no level bits. build_game.py takes --sysroot, build_hactool.py --cc and
build_xlate.py --llvm/--sysroot; linux.c carries the Linux 6.7 write-watch definitions for older headers.
Also: shader_census.py and package_build.py use the Linux executable names, and probe-shader writes its shader path with
forward slashes.
