AnBox86_64 was tested on Amazon HD Fire 10 (Termux uname -m = aarch64, proot `uname -my = aarch64) but not Retroid Pocket 2 (armv7l).
Box64 is not detected with armv7l, so wine64 and its wineserver are not usable.
We may need a cpu detector routine which then switches to a variant the older AnBox86 script if needed.
