This causes warnings when using TCG (i.e. no KVM):
qemu-system-i386: warning: TCG doesn't support requested feature: CPUID.80000001H:EDX.syscall [bit 11]
qemu-system-i386: warning: TCG doesn't support requested feature: CPUID.80000001H:EDX.lm [bit 29]
The '-cpu' flag was added to support using prebuilt GCC toolchains in
Buildroot in commit 344ff00 ("boot-qemu.sh: Use Nehalem for non-KVM boot
on x86_64") but I forgot that this block applies to both 32-bit and
64-bit x86.
Given that Nehalem is a 64-bit microarchitecture, this flag should only
be supplied when booting an x86_64 kernel, which removes the warning for
-a x86.
