Since the addition of root password setting support in buildroot, there have been a few bug reports in this area ([1], [2]). In these cases, the system mkpasswd did either not work, or did not provide the options we expect, like -m <method>. This patch adds a mkpasswd host package, based on the sources from whois. When a non-empty root password is set, this package is used as a dependency.
