I've confirmed libgcrypt-1.8.4.tar.bz2 can compile.
The following commit removed the memcpy of _gcry_aes_ssse3_do_setkey.

I've found openSUSE is working around a similar issue by setting -U_FORTIFY_SOURCE to CFLAGS.

I've confirmed this trick can address the issue of libgcrypt-1.7.6.tar.bz2 for me.
