Pine64 native system rebuild success

[Daniel Engberg]

Hi Milan,

I've also experimented with this a bit on both ARMv7 and ARM64/AARCH64 
and added two pages to the wiki about this which may be of interest and 
to make information more easily available.

The boards I've been using myself are Orange Pi PC and PC 2 and both 
work very well so impressive work done by all developers and 
contributors.

Best regards
Daniel
