Thanks!

Except if we manage to convince host-libtirpc that it should just
install the RPC headers, and not do anything that needs rpcgen.

If I remember correctly, it's because it needs to generate the C code
matching those RPC descriptions:

./tirpc/rpc/rpcb_prot.x
./tirpc/rpcsvc/crypt.x
./tirpc/rpcsvc/key_prot.x

But it's been a very long time I did this, and libtirpc has been
updated multiple times since then.

Alternatively, one approach would be to bundle a pre-generated version
of those C files instead of having to run rpcgen. Not the nicest
solution, but that's one solution.
