m4: disable -Wmissing-braces for newer clang
src/NetworkManagerUtils.c:347:18: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces]
NMIPAddr a1 = { 0 }, a2 = { 0 };
^
{}
Should we initialize unions this way? I think it's all right -- the initializer
works well and { { { 0 } } } is probably not what we'd like to see.
