TCP mount of nfs seems to be broken.
# mount bar:/usr /mnt
[tcp] bar:/usr: RPCPROG_NFS: RPC: Unknown protocol
I tracked this down to lib/libc/rpc/rpcb_clnt.c. Seems like
the problem is in __rpcb_findaddr_timed().

} else {
client = getclnthandle(host, nconf, &parms.r_addr);
Notice how newnconf, the second arg of getclnthandle(), is
derived. Previously it was the output of getnetconfigent()
while now it is output of __rpc_getconf(). It expects its
arg to be of type ``struct handle*'', but it is given an arg
of type ``struct netconfig*'' The two structs are not congruent.
I don't really understand this code so I don't know what the real
fix is.
