commit f52c40680f0aad44b9ae16648803453ec00cbb2c
Author: Paul Crawford <psc@sat.dundee.ac.uk>
Date:   Fri Dec 30 15:55:45 2016 +0000

    Compile with musl when nfs is disabled
    
    musl does by default not ship with rpc headers. The watchdog should
    not require rpc headers when nfs support is disabled.
