Support dynamic dual/quad loop selection on aarch64
Currently, there are three variants available on aarch64, qdf24xx, thunderx2t99, and cortex-a72.
-DCLIB_N_PREFETCHES is passed to source code to select dual/quad implementation.
Besides, different compiler options are applied on these critical functions.
gcc-7.3.0 reports ICE(internal compiler error) with -mtune=thunderx2t99,
so -mtune=thunderx2t99 is enabled only when gcc version is greater than 7.3.0
