Build issue on macos12.6

[t20100]

Failed to build with macos12.6 on a x86_64 CPU, python3.10 with default build options.

First error:

clang: error: the clang compiler does not support '-march=native'

This option was apparently not available for clang on ARM before v15.0.0

Using HDF5PLUGIN_NATIVE=False fixes it error, but build fails later with:

src/c-blosc/blosc/bitshuffle-avx2.c:22:4: error: AVX2 is not supported by the target architecture/platform and/or this compiler.
...

This seems to be due to building fat library (-arch arm64 -arch x86_64 options) with initial option detection being run only on host architecture.
