With objtool enabled, below warnings are seen when trying to build:

drivers/crypto/vmx/aesp8-ppc.o: warning: objtool: aes_p8_set_encrypt_key+0x44: unannotated intra-function call

drivers/crypto/vmx/aesp8-ppc.o: warning: objtool: .text+0x2448: unannotated intra-function call

drivers/crypto/vmx/aesp8-ppc.o: warning: objtool: .text+0x2d68: unannotated intra-function call

Skip objtool from running on this file, for two main reasons:

Since this file comes from OpenSSL, and since it is a perl file
which generates a .S file, it may not be the best choice to
make too many code changes to such files, unless absolutely
necessary.

Second reason is that, at least as far as the objtool --mcount
functionality is concerned, we do not have to run objtool on
that file because that file does not have any calls to _mcount.
