[libvirt] [PATCH 1/1] qemu: avoid users specifying CPU features for non-x86 plaftorm.

From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com&gt; Currently, only X86 provides users CPU features with CPUID instruction. If users specify the features for non-x86, it should tell users to remove them. This patch is to report one error if features are specified by users for non-x86 platform.
