Box64cpu does not work on Snapdragon 845

[alexvorxx]

System Details

Snapdragon 845, Termux.

Wine Hangover version 8.21 and higher.

Problems Description

Box64cpu does not work.

01ac:err:environ:init_peb starting L"D:\\Programs\\wordpad.exe" in experimental wow64 mode
starting Box64 based box64cpu.dll
01ac:err:virtual:virtual_setup_exception stack overflow 1312 bytes addr 0x79f15e00 stack 0x100100ae0 (0x100100000-0x100101000-0x1001ffd20)

Apparently the problem is due to function box64_detect_cpu_features()
https://github.com/AndreRH/wine/blob/hangover-8.21/dlls/box64cpu/cpu.c#L798
When I commented out this line, box64 started working.

This problem exists on Snapdragon 845, but on Snapdragon 870 box64cpu works fine.

P.S. Can you please add environment variables to box64cpu?

It's so easy, I'd expect a pull request, there's even reference code for QEMU_LOG. A proper issue for that topic would also be a good idea, so I can mark it as "good first issue"
