target-i386: Set "check=off" by default on pc-*-2.4 and older
The default CPU model (qemu64) have some issues today: it enables some features (ABM and SSE4a) that are not present in many host CPUs. That means many hosts (but not all of them) had those features silently disabled in the default configuration in QEMU 2.4 and older. With the new "check=on" default, this causes warnings to be printed in the default configuration, because of the lack of SSE4A on all Intel hosts, and the lack of ABM on Sandy Bridge and older hosts: $ qemu-system-x86_64 -machine pc,accel=kvm warning: host doesn't support requested feature: CPUID.80000001H:ECX.abm [bit 5] warning: host doesn't support requested feature: CPUID.80000001H:ECX.sse4a [bit 6] Those issues will be fixed in pc-*-2.5 and newer. But as we can't change the guest ABI in pc-*-2.4, disable "check" mode by default in pc-*-2.4 and older so we don't print spurious warnings.
