There are various QA_something_something which silence the warning, I'm
not saying they have to actually fix the cflags issue but I want to not
get warned when I shouldn't, like on prebuilt stuff like this.

I actually didn't intend to paste that error, I was only trying to get
the cflags ones, but since you mentioned it, I'm sure there is a
QA_something to silence that error or, you know, dosym.  Users shouldn't
see QA warnings, those are for devs to fix before committing.
