On amd64 OPENSSL_cpuid_setup and OPENSSL_ia32cap_P are now hidden so we don't
have to go through the PLT/GOT to get at them anymore. In fact going through
the GOT now fails since we no longer have a GOT entry for OPENSSL_ia32cap_P.
Fixes the problem spotted by jasper@ and sthen@. Based on a diff from mikeb@
who did most of the actual work of tracking down the issue.
ok millert@, mikeb@
