Android UCI engine update: Ethereal 8.85.ACH

After yesterday's post which included several Ethereal versions, Alexei has kindly provided his compile of v8.85. including the 64-bit arm8 alternative as a much faster bonus.

As expected, ACH build performed way faster than Andy's on my MTK6752 using 4 out of 8 cores. 763 knps vs 569 knps means 1.34x speedup, thanks to LTO and PGO optimizations of the build. The increase is equivalent to +17 ELO over the original if we assume that each doubling adds +40 ELO.

GET Ethereal 8.85.AG for arm7 (was posted yesterday)
GET Ethereal 8.85.ACH for arm7 and arm8
