Bug#995005: xsimd: Built with -march=native

[James Cowgill]

Source: xsimd
Version: 7.5.0-1
Severity: serious

Hi,

>From the i386 build log:

You must not build Debian packages with the -march=native build flag
because then the package will only work on the same CPU architecture as
the build machine.

I would guess that amd64 is also affected (although there is no build
log so I can't check).

Thanks,
James
