Changes in v6:
- Use update_guest_debug in system mode, rather than a tcg-specific hack
in cpu_single_step. This would also be required for split-accel, if
and when that project gets regoing.
Unfortunately, cpus_get_accel() can't be used in user mode, so
fix things with an ifdef.
- Hide other cflags updates behind tcg_enabled(), so that even if
tcg is built in, we don't use it when using virtualization.
This also means we don't need stubs, because tcg_enabled() will
reduce to constant false with --disable-tcg.
