Fix compilation on armv5

Browse Source 
Two changes broke compilation on armv5, where we're currently
not CI-testing:

634f82f1f1 changed the signature
in a function definition without changing its declaration, while
it was actually intending to add this as a new overload.

bfe0db6fbe added an #error
condition without fixing compilation on armv5. I don't know
if the fix is correct, but at least it compiles.

Task-number: QTBUG-37034
