Frame pointers are completely broken by vmenter.S because it clobbers
RBP:
arch/x86/kvm/svm/vmenter.o: warning: objtool: __svm_vcpu_run()+0xe4: BP used as a scratch register
That's unavoidable, so just skip checking that file when frame pointers
are configured in.
On the other hand, ORC can handle that code just fine, so leave objtool
enabled in the !FRAME_POINTER case.
