Also RTMIN and RTMAX are different.

This code is copied from docker.

Is there a way to cross build on these platforms to make sure we don't regress?
LGTM

[Luap99]

I don't know. The normal cross compile with go does not work because of c dependencies so I assume we would need a mips vm.

@dangowrt Thanks for checking. This should be fixed now.

[rhatdan]

@Luap99 Ok, just checking. These issues tend to creep in over time.
