Fixes warnings in builds using core2-32 tune: warning: TCG doesn't support requested feature: CPUID.80000001H:EDX.syscall [bit 11] warning: TCG doesn't support requested feature: CPUID.80000001H:EDX.lm [bit 29] when executing postinsts using qemu-i386. i386 target doesn't enable CPUID_EXT2_SYSCALL and CPUID_EXT2_LM [1] while cpu choice of core2duo that we use for core2-32 TUNE does [2]. Use n270 cpu instead to use with qemu which supports SSSE3 and doesn't have these bits enabled [3].
