Currently target binaries contain support for all OS/arch combinations. However, obviously a fuchsia target binary won't test windows. For target binaries we need support only for a single target (with the exception of 386/arm target in amd64/arm64 binaries). So compile in only _the_ target into target binaries. This reduces akaros/amd64 fuzzer binary from 33 to 7 MB and execprog from 28 to 2 MB.
