Add Aarch64 assembly implementation of Camellia
* cipher/Makefile.am: Add 'camellia-aarch64.S'. * cipher/camellia-aarch64.S: New. * cipher/camellia-glue.c [USE_ARM_ASM][__aarch64__]: Set stack burn size to zero. * cipher/camellia.h: Enable USE_ARM_ASM if __AARCH64EL__ and HAVE_COMPATIBLE_GCC_AARCH64_PLATFORM_AS defined. * configure.ac [host=aarch64]: Add 'rijndael-aarch64.lo'.
Patch adds ARMv8/Aarch64 implementation of Camellia.
