powerpc-utils/powerpc-utils-warnings.patch

There are several build warnings generated when building the powerpc-utils
package, most of these are just innocuous initializations of variables.
There are a couple of larger changes such as in serv_config.c where the
results of the fread call needed to be properly checked.
