In de5553aa, qmake was fixed to resolve QMAKE_INFO_PLIST based on the
current pwd to fix QTBUG-21267. This fix was lost as part of 8c138054
in 5.4.
This fixes the error:
"WARNING: Could not resolve Info.plist ..."
when using qmake for shadow builds on OS X.
[ChangeLog][qmake][OS X/iOS] Fixed QMAKE_INFO_PLIST path resolution
