#2 Make NIS and DES optional

[Anonymous]

I'd like to use libtirpc in an embedded system where modern glibc no longer exports an RPC interface. But I don't need or have NIS or DES libraries on the system. It would be nice if libtirpc would detect that NIS and DES interfaces are not installed and disable their use. Or at least expose a manual enable control for these in the configure script.
