`xmlrpc-c-config $modules --cflags` may report no `-I` flags if the headers are in a standard location like `/usr/include`. In this case it is okay for `XMLRPC_INCLUDE_DIRS` to be empty. Ideally the `--cflags` output should be used as hints for a `find_path` call to really find the headers as we do for other find modules, but simply assuming no explicit include directories are needed is good enough for now. Fixes: #17347
