-march=native is a baseline violation on architectures where it is supported, and causes a FTBFS on architectures where it is not supported. It also changes the set of architectures where the package might run based on the capabilities of the buildd, e.g. on amd64 code built on an AMD buildd might not run on Intel hardware and code built on Intel hardware might not run on AMD hardware.
