CppApplication fails to build Android apk

From Qt 5.14 qbs can generate multi-arch apk containing Qt libraries using multiplexing.

The QtApplication item is a CppApplication which has a depend on "Qt.core" AND ad "_abi" to the targetName of the product.

So directly using a CppApplication with a depend on "Qt.core" is not equivalent to using a QtApplication and fails on Android.

Properties {
    condition: isForAndroiFaild && Qt.android_support._multiAbi
    targetName: name + "_" + Android.ndk.abi
}

The simplest solution I see is to test if qbs is actually multiplexing in Application.qbs and update the targetName there.

The only side effect I see is when using qbs without Qt in a multi-arch environment: the generated libraries will have the _abi in their name.

The code generated by the qtc wizard is also using the CppApplication item and consequently fails on Android.
