[PATCH] silent: Set AM_DEFAULT_VERBOSITY for compatibility on older automake

[Dan Nicholson]

Custom silent rules will become recursive on older automake where
AM_SILENT_RULES is not included. Set AM_DEFAULT_VERBOSITY in this
fallback case for compatibility.

 I hit this error in xts when a couple people tried to run the test
 suite against older hosts.
