Now I have the curious problem that I have the "normal” rpc.h on my host system (linux-x86_64)
and therefore there with TIRPC=YES then the libtirpc.so of course is not found.
But I have to use the rpcgen of den linux-host to generate the vxi11core_xdr.c
And the host includes of course rpc/rpc.h which is then not found by linux-ppc64e6500.
