Build for Debian MIPS

[Marcin Dulinski]

Hi

I built a bird for edgerouter using these debian images:
https://people.debian.org/~aurel32/qemu/ sometimes you can specify cpu type
but for edgerouter is quite slow... So I used emdebian.org but it looks
down. I think you can find docker images for each platform.
You can try use: https://wiki.debian.org/CrossToolchains


Regards,
Martin
