remove RPC implementation
The included RPC implementation is ipv4 only. Other C library projects have either deprecated the internal RPC implementation (GNU C Library) or never implemented such functionality (musl C Library). The latest rpcbind release (0.2.4) checks for libtirpc and does not allow to be build with uClibc-ng RPC without patching. The common use case for RPC nowadays is to use rpcbind together with nfs-utils to provide NFS server or client support to a system. The included RPC implementation does create issues with duplicate symbol failures when statically compiling with RPC enabled.

- * XDR provides a conventional way for converting between C data
- * types and an external bit-string representation. Library supplied
- * routines provide for the conversion on built-in C data types. These
- * routines and utility routines defined here are used to help implement
- * a type encode/decode routine for each user-defined type.
- *
- * Each data type provides a single procedure which takes two arguments:
- *
- * bool_t
- * xdrproc(xdrs, argresp)
- * XDR *xdrs;
- * <type> *argresp;
- *
- * xdrs is an instance of a XDR handle, to which or from which the data
- * type is to be converted. argresp is a pointer to the structure to be
- * converted. The XDR handle contains an operation field which indicates
- * which of the operations (ENCODE, DECODE * or FREE) is to be performed.
- *
- * XDR_DECODE may allocate space if the pointer argresp is null. This
- * data can be freed with the XDR_FREE operation.
- *
- * We write only one procedure per data type to make it easy
- * to keep the encode and decode procedures for a data type consistent.
- * In many cases the same code performs all operations on a user defined type,
- * because all the hard work is done in the component type routines.
- * decode as a series of calls on the nested data types.
