Android's toolchain file, ie., android-legacy.toolchain.cmake assumes that the default build is a Debug build, and it adds the `-g` flag to CMAKE_<LANG>_FLAGS, as a result, our release Android build always contains debug symbols. In this patch, I basically move the `-g` flag from CMAKE_<LANG>_FLAGS to CMAKE_<LANG>_FLAGS_DEBUG, and CMAKE_<LANG>_FLAGS_RELWITHDEBINFO. Pick-to: 6.5 6.6 Fixes: QTBUG-111901 Change-Id: I31eadb07d9172c923e8beaf0ac6c6e34fe1ebefb Reviewed-by: Joerg Bornemann <joerg.bornemann@qt.io>
