[PATCH roland/sunrpc] Exclude rpcent functions and NSS backends for rpc, key when excluding sunrpc.


The rpcent functions (from <rpc/netdb.h>) are useless in a C library that
does not include sunrpc support.  The getpublickey function was already
excluded, but its NSS backends were not.  

This change just moves around and conditionalizes the code so that those
are left out when sunrpc is also left out entirely.  It has no effect on
existing configurations, which still build in sunrpc.  A future follow-on
change that should be made eventually is to make the rpcent functions
unlinkable like the rest of sunrpc, when compiling a compat configuration
without --enable-obsolete-rpc.

Tested with 'make check-abi' on i686-linux-gnu and x86_64-linux-gnu.

If nobody objects, I'll commit this on Tuesday.


Thanks,
Roland
