This fixes the build on 9, which has failed ever since it was added to the
tree.
From the fallout logs:
CMake Error at src/crypto/mac/ghash/pclmulqdq/CMakeLists.txt:9 (message):
WITH_MAC_GHASH_PCLMULQDQ enabled, but there is no compiler support for
-mpclmul
This happens because GCC 4.2.1 in base (the default compiler) does not
support the -mpcmul option.
Fix it by disabling the module when on FreeBSD < 10 (i.e. when base GCC is
the default compiler).
