Dear Maintainers,
I recently updating LXQt to new upstream release which uses Qt6. And I
got salsa-ci detected FTBFS with following message on i386:
```
/usr/include/i386-linux-gnu/qt6/QtCore/qfloat16.h: In member function
‘constexpr qfloat16::operator NativeType() const’:
/usr/include/i386-linux-gnu/qt6/QtCore/qfloat16.h:64:52: error: SSE register
return with SSE2 disabled
64 | constexpr operator NativeType() const noexcept { return nf; }
| ^
/usr/include/i386-linux-gnu/qt6/QtCore/qfloat16.h: In function ‘qfloat16
operator+(qfloat16, qfloat16)’:
/usr/include/i386-linux-gnu/qt6/QtCore/qfloat16.h:124:147: error: operation not
permitted on type ‘_Float16’ without option ‘-msse2’

```

Not sure if this a false detection or something wrong in Qt6 package.
The LXQt package used to builds fine with Qt5.
Best regards,
