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.
