title: How to build 32-bit Qt5 application on 64-bit Ubuntu
body: <p>I have currently got the 64-bit version of Qt5 installed on a 64-bit Ubuntu machine but I'd also like to be able to do 32-bit builds on the same machine. On Windows I can simply select additional kits in the MaintenanceTool but on Linux this doesn't seem to be possible. Or am I missing something?</p>
