Subject: [PATCH 3/4] rcutorture: Make -soundhw a x86 specific option

The option "-soundhw pcspk" gives me a error on PPC as follow:

qemu-system-ppc64: ISA bus not available for pcspk

, which means this option doesn't work on ppc by default. So simply make
this an x86-specific option via identify_qemu_args().
