    sunrpc: Remove stray exports without --enable-obsolete-rpc [BZ #23166]
    
    This is needed to avoid a warning when linking against libtirpc:
    
    /lib64/libc.so.6: warning: common of `rpc_createerr@@TIRPC_0.3.0' overridden by definition
    /usr/lib64/libtirpc.so: warning: defined here
    
    This ld warning is not enabled by default; -Wl,--warn-common enables it.

    (cherry picked from commit 89aacb513eb77549a29df2638913a0f8178cf3f5)
