Dear Maintainer,

isospec failed to build ppc64el and riscv64 due to -march=native:
https://buildd.debian.org/status/fetch.php?pkg=isospec&arch=ppc64el&ver=2.2.3%2Bcleaned1-1&stamp=1761070922&raw=0
https://buildd.debian.org/status/fetch.php?pkg=isospec&arch=riscv64&ver=2.2.3%2Bcleaned1-1&stamp=1761101061&raw=0

I proposal one patch below and test it on riscv64:

 cmodule = Extension('IsoSpecCppPy',
