[ARM] Select appropriate memcpy implementation for ARMv8-a.
The newlib configury logic that detects architecture version and
chooses an appropriate memcpy implementation does not consider
ARMv8-a.
This patch adds configury logic to detect ARMv8-a along with the
associated changes in Makefile.am and memcpy.
