Done.

Done.

I added "%current-target-system" to support cross-compilation.
Also fixed the drunk "string?=" uses - there's "string=?" actually and
I replaced it with "string-prefix?".

What's the difference between "arm-linux-gnueabihf" and
"aarch64-linux-gnu"? Are they synonyms?
Should it be:
if "arm-linux-gnueabihf" or "aarch64-linux-gnu"
use "--arch=armhf-linux"?

I want to try anyway. Jami supports Raspbian, so it is worth trying.
