Hi,
To solve this issue it is possible to use xxd + gcc to create object file with
appropriate flags.
Similar solution is proposed for kvmtool:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=827525
The patch that fixes this issue is attached.
Using this patch I was able to build mbr for mips64el.
It is tested on i386 as well.
Regards,
Dejan
