[coreutils] Coreutils Solaris extensions

[John Sonnenschein]

We are considering extending some of the utilities in GNU Coreutils to 
provide support for some of the newer Solaris features.  We would like 
to discuss if you'd consider accepting these additions upstream.  If 
that is possible, we'd like to get your guidance on about how best to 
achieve that goal.

As an example, we could add NFSv4 ACL support to Coreutils which would 
benefit all platforms that support NFSv4 or ZFS (eg, FreeBSD), not just 
Solaris.

Thanks
