Android SDK installation error if using NDK (Side by side) only

Qt Creator 4.12.0 shows the following alert when having the NDK installed in /sdk/ndk/<version> ("NDK (Side by side)" in Android SDK Manager), but not in the old /sdk/ndk-bundle location ("NDK (Obsolete)" in Android SDK Manager in the latest Android Studio):

Android SDK installation is missing necessary packages. Do you want to install the missing packages.

Additionally, the panel will show "Android settings have errors" and the error " All essential packages installed for all installed Qt versions". Clicking "Yes" will install the "NDK (Obsolete)" package in /sdk/ndk-bundle.

Having only the "NDK (Side by side)" installed should not be treated as an error.

Steps to reproduce

1. Install the latest Android Studio version
2. In SDK Manager > SDK Tools:
   • Check "NDK (Side by side)"
   • Make sure that "NDK (Obsolete)" is unchecked (disable the "Hide Obsolete Packages" checkbox to see this package)
3. Run Qt Creator 4.12
4. Go to Settings > Devices > Android

Expected results

No error is shown.

Actual results

The above error is shown, even though the NDK installation is correctly detected in ~/Library/Android/sdk/ndk/21.1.6352462.
