When using qemu's linux-user binaries through binfmt, argv[0] gets lost along the execution because qemu only gets passed in the full file name to the executable while argv[0] can be something completely different. This breaks in some subtile situations, such as the grep and make test suites. This patch adds a wrapper binary called qemu-$TARGET-binfmt that can be used with binfmt's P flag which passes the full path _and_ argv[0] to the binfmt handler. The binary would be smart enough to be versatile and only exist in the system once, creating the qemu binary path names from its own argv[0]. However, this seemed like it didn't fit the make system too well, so we're currently creating a new binary for each target archictecture.
