Can we consider what I did in this PR instead #71 I find to easier to have the restrictions for an host in a single file rather than mixed with all the targets. It would also make it easier to have modifiers a for a host added later.

Can we consider what I did in this PR instead #71 I find to easier to have the restrictions for an host in a single file rather than mixed with all the targets.

But puting all blacklist in one place give us the whole picture and the difference between host quickly.

It would also make it easier to have modifiers a for a host added later.

I am thinking to change blacklist to regex pattern instead using config as regex, then we don't need change the match anymore and write the complex parttern, e.g.: -sim:nsh,(Linux)|(Darwin).

Merged OS side, just restarted the build.
