It was including this file unconditionally. Now it should be ok (only
included if --enable-cryptodev is specified). If you have a cpu with
crypto accelerator that is supported by linux (via and some amd geode
cpus have), and you use cryptodev you should get quite a difference. For
some reason I get big difference by using the kernel aes implementation.

PS. I cannot seem to get how configure.ac works now. I have added a
cryptodev test in configure.ac (global), but the ENABLE_CRYPTODEV
definition is only in root config.h and lib/config.h does not have it
(gnutls_int.h doesn't include the root one). How can I add a check like
that?
