The warning is

target/s390x/misc_helper.c:209:21: error: suggest
      braces around initialization of subobject [-Werror,-Wmissing-braces]
    SysIB sysib = { 0 };
                    ^
                    {}

While the original code is correct, and technically exactly correct
as per ISO C89, both GCC and Clang support plain empty set of braces
as an extension.
