 (Raspberry Pi B+)

 This might be interesting, the compile condition within
 libgcrypt-1.8.0/cipher/rijndael-armv8-aarch32-ce.S is:
 
 #if defined(HAVE_ARM_ARCH_V6) && defined(__ARMEL__) && \
     defined(HAVE_COMPATIBLE_GCC_ARM_PLATFORM_AS) && \
     defined(HAVE_GCC_INLINE_ASM_AARCH32_CRYPTO)
 
 Though obviously, this file requires armv8, not just armv6. Looking at
 config.in, it seems that ENABLE_ARM_CRYPTO_SUPPORT should be included in
 the condition to prevent it from being built, I'll try and see if it helps.
