Mismatched checksum on M1+ macs

[Ch0ronomato]

Hi!

I recently got the rom setup and had a mismatched checksum. This was the checksum for the generated rom

(venv) ➜  fzerox git:(main) md5sum build/fzerox.us.rev0.z64 
472d3db4124bec12c8212f399f0274fc  build/fzerox.us.rev0.z64

I poked @inspectredc on the discord and found out that on mac, Torch needed an additional compiler flag to treat the floating point values different. This is the diff to tools/Torch/CMakeLists.txt

diff --git a/CMakeLists.txt b/CMakeLists.txt
index 3b29309..231bcb0 100644

+    set(CMAKE_CXX_FLAGS "-Wno-narrowing -ffp-contract=off")
 else()

After making this change, the checksums matched.
