Cannot build Qt for Android on Apple M1

When trying to build the 6.2.5 branch (cbd0fab75f0343c61fcda5fe604ba88fb51cb797 of tqtc-qtdeclarative) , one get following build error

```
/Users/sami/projects/tqtc-qt6.2.5/qtbase/src/corelib/global/qlogging.cpp:1307:13: error: use of undeclared identifier 'backtrace' int n = backtrace(buffer.data(), buffer.size());
```
when building on a macbook pro.
 
The build was configurated using
```
../tqtc-qt6.2.5/configure -platform android-clang -android-ndk /Users/sami/Library/Android/sdk/ndk/24.0.8215888 -android-sdk /Users/sami/Library/Android/sdk -qt-host-path ../tqtc-qt6.2.5-build/qtbase -android-abis x86 -developer-build
```
and the android stuff was installed using android studio (see attached screenshot).
The error can be disabled by undef'ing the QLOGGING_HAVE_BACKTRACE flag.
