When it's a full replacement, we should also work out how to stop as much 
as possible of the deprecated code from being built at all for future 
architecture ports (so that for ports whose lowest symbol version is 
GLIBC_2.24 or whatever, the symbols don't exist in the glibc ABI even as 
compat symbols and --enable-obsolete-rpc isn't allowed at all).
