I didn't find a way to suppress them. It would be nice to have options similar to the -D/-d options to be able to filter and/or redirect the output. My use case is chroot/container execution for different architectures via binfmt. In this case it will appear as if the binary in question had emitted messages like "Unsupported setsockopt ..." to stderr while in fact the message came from qemu-*-static.
