Jürgen Buchmüller 05abaf453c qt5: musl libc main thread stack bottom calc
For musl libc, just as for Android, the main thread pretends
to have a tiny stack space. Add a patch based on the one
found at: https://bugreports.qt.io/browse/QTBUG-44268

Closes #3965

For musl libc the stackBottom for the main thread is recalculated
just as it is for Android. See: https://bugreports.qt.io/browse/QTBUG-44268
