Thanks for looking into this issue.  I see you wound up substituting
-march=native, which is no better:

* It still limits the portability of the resulting binaries.
* It is also available only on x86.
* It affects reproducibility, because binaries will vary depending on
  the precise CPU type of the build system.

Could you please not pass any -march flag?

Thanks!
