make: Automake is complaining about .PRECIOUS being redefined

Yesterday I added test-suite.log as dependency to the .PRECIOUS
target. Automake is warning about this target being redefined
and from what I see there is no way I can stop the warning but
I can add the %MAKEFILE% as dependency.

automake warning:
Makefile.am:35: warning: user target '.PRECIOUS' defined here ...
/usr/share/automake-1.13/am/configure.am: ... overrides Automake target '.PRECIOUS' defined here
journal: Leave server_dispatch_message early when Storage is none

When using Storage=none there is no point in collecting all the
information just to throw them away. After this change journald
consumes a lot less CPU time. It still consumes more CPU time to
forward a message than Busybox's syslogd to save the entire message
to a file and rotate it.
