I know,I sent the patch only for explaining better the issue,
I didn't plan at any moment to use that patch.
I just wanted an howto,in order to use the site files.

I tested the default running the tests,that is to say:
devshell,copy-paste the test,compile them,run them on target.

That's exactly what I wanted to do,but unfortunately as I said in the
first mail:
*I'm not confident with it
*I bet it needs review before touching it
*I wouldn't know in which file I should add the changes(Maybe
common-glibc?)

I didn't know that I needed to do that,
thanks a lot,
I'll try to find out how to do it.
