* 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.
