Hi Martin,

Yes, rewriting them is probably too hard to do reliably. Simply forcing jobs 
with -march=native or -mtune=native to run locally is easy enough; I've added 
a patch that does just that, which I tested locally.

Note that -mtune=native does not result in broken binaries, but it may result 
in code that is optimized for a different cpu than specified, so it's 
probably best to run jobs with this option locally as well.

Kind regards,
Maks Verver.
