Why should Qbs care about the predefined macros? Qtc needs them for the
code model, but it passes -m flags (at least now with
https://codereview.qt-project.org/254118).

So in the kit you can set the default ABI (if any, or unknown otherwise),
and the code model will pick up the correct ABI according to the compiler
flags.
