[pgpool-committers: 7978] pgpool: Fix "ar: `u' modifier ignored since `D' is the default (see `U'

[Tatsuo Ishii]

Fix "ar: `u' modifier ignored since `D' is the default (see `U')" warnings.

The warning can be eliminated by changing arguments of ar command from
"cru" to "cr".  There were two places of the warnings: src/libs/pcp
and src/watchdog.  For the former, we need to fix libtool, which is
generated by configure. So fix configure.ac.  For the latter, just fix
src/watchdog/Makefile.am.
