[Toybox] [TOYBOX][RFC] building toybox on a Yocto enviroment

[José Bollo]

I had the issue a long time ago and it seemed that it came from cross
compiling environment.

It was not properly set.

I submitted the patch below to Rob (original version was 0.6.0 not
checked since).
In the hope that it helps
Best Regards
José Bollo
