The install_pmda Makefile target was completely broken.

Amitay and I just hacked up the build/packaging config for this:

* CTDB pmda support is no longer built unless you configure with
  --enable-pmda

* A ctdb-pcp-pmda RPM is build if you do:

    ./packaging/RPM/makerpms.sh --with pmda

  The default is not to build this.

The defaults are "no" because we want to avoid unexpected build
failures.  We have tested on RHEL with the EPEL pcp-libs-devel and will
make sure it is installed on our local test build system, where we
build and test every night.

Should be pushed soon...

At some stage we should also push our autotest scripts as part of either
CTDB or autocluster...

peace & happiness,
