Enable hardware acceleration for ARMv8 targets.
When ARMv8 hardware acceleration is enabled on AArch64 without any
additional flags, the build fails with the following messages:

make[3]: *** [Makefile:3801: wolfcrypt/src/port/arm/src_libwolfssl_la-armv8-aes.lo] Error 1
This is because of some inline assembly in parts of the AES structure
using the "m" constraint.
So lets use the flag -mstrict-align to prevent this error.

[Thomas: restrict the -mstrict-align workaround to AArch64, as ARMv8-A
can also be used in an AArch32 build, and in this case, gcc doesn't
support the -mstrict-align flag]
