• store the output of build_cmd run in a separate build log file (grep the plugins for log_filename, use sdist_root_dir.parent), so we have the output in a log file. Right now we only have a build.log with the wheel build step.
• update to latest version
• prevent builds on CUDA, ROCm, and other archs. You can either do that in the plugin or by adding a constraint onnxruntime<0.0 to the constraints files for CUDA, ROCm, and so on. The constraint solution is more flexible.
• verify that the build works on x86_64v3 and does not require AVX512 instructions. I see nnxruntime/core/mlas/lib/q4gemm_avx512.cpp.o in the output. Does onnxruntime detect CPU features at runtime or will it fail on x86_64v3 machines without AVX512?
• In the build process there are some 
  CMake vars to enable / disable ISA features:

./cmake/CMakeLists.txt:option(onnxruntime_USE_AVX "Use AVX instructions" OFF) 
./cmake/CMakeLists.txt:option(onnxruntime_USE_AVX2 "Use AVX2 instructions" OFF) 
./cmake/CMakeLists.txt:option(onnxruntime_USE_AVX512 "Use AVX512 instructions" OFF)

We should enable AVX and AVX2 and keep AVX512 disabled.
