on non-apple arm devices it assumes there is sys/auxv.h and
asm/hwcap.h and uses getauxval(AT_HWCAP) to see if some features
(CRC32, SHA1, SHA2 and AES) are supported by the CPU.
This is probably the smallest fix, but it unconditionally disables the
use of the cpu instructions. I don't have an aarch64 machine atm and
can't test.
What can we use to detect the availability of these instructions?
