[Bug 50229] Battle.net launcher sometimes crashes after login (wine-5.22)

[WineHQ Bugzilla]

--- Comment #13 from Sveinar Søpler  ---
This "AVX" issue is mostly for 32-bit binaries, and battle.net launcher is a
32-bit app.

https://sourceforge.net/p/mingw-w64/discussion/723797/thread/bc936130/

My theory would be - although probably a bit far fetched - that now that wine
uses a lot more dll libs compiled as PE libs with mingw, SOME functions could
cause issues with 32-bit apps if you compile with any -mavx or -march=native
(given a recent processor) optimizations.

There is a bit of "default flags" changed for mingw-w64-9.3 -> mingw-w64-10.2
from what i can see, that could possibly cause issues when using the "same
flags i have always done" after upgrading perhaps.
