Cross-building ports with release(7)

[Mori Hiroki]

Hi

ZRouter.org support ports cross build.

https://zrouter.org


I do build mips, mipsel, arm, armv7 ports by ZRouter.

I put paper to AsiaBSDCon 2020 about cross build ports.
The paper is accept. But AsiaBSDCon is cancelled.

This is prepared slide.
