* configure.in: Fix test for STRUCT_RPCENT_ALREADY_PROVIDED if

		there happens to be a /usr/include/rpc/netdb.h.  This
		causes /usr/include/netdb.h to include netdb.h from our
		tree rather from /usr/include/rpc, which of course results
		in massive damage.  Basically, if /usr/include/netdb.h
		contains rpcent declaration and /usr/include/rpc/netdb.h
		exists, then assume that there is no struct rpcent in the
		system include files.  It's really unfortunate that we
		need to do this at all, but it's all we can do short of
		renaming a bunch of include files or directories.
