The armv8 architecture spec has both aarch32 (32-bit) and
of Aarch32 execution environments on Aarch64. I'm
not trying for that test case at the moment).

-mfpu=neon-fp-armv8 is an arm (32-bit) compiler option. T
++ -DDEBUG -g3 -O0 -mfpu=neon-fp-armv8 -fPIC -pipe -c cryptlib.cpp

It looks like -mfpu=neon-fp-armv8 is a GCC 4.9 feature
(http://gcc.gnu.org/gcc-4.9/changes.html), and Linaro
