Bug#1081057: xsimd builds with -march=native

[Matthias Klose]

Package: src:xsimd
Version: 13.0.0-1
Severity: serious
Tags: sid trixie

xsimd builds with -march=native, at least on amd64 and arm64. This is a 
policy violation.

and even if you build multiple variants, -march=native never is the 
correct configuration to build packages for, assuming that the user's 
machine have at least the same baseline as the build machine.
