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.
