Commit 9a400068a158 ("KVM: selftests: x86: Avoid using SSE/AVX instructions") unconditionally added -march=x86-64-v2 to the CFLAGS used to build the KVM selftests which does not work on non-x86 architectures:

cc1: error: unknown value ‘x86-64-v2’ for ‘-march’

Fix this by making the addition of this x86 specific command line flag conditional on building for x86.

Best regards,

I see this patch is already in Linus' tree, but anyway
