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].

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
