default target in generated makefiles

When using Qt 4.6.2, the default target of makefiles generated by qmake (with debug_and_release configuration) is the release one. So, when running make without arguments the release version of app is built.

However, in newer Qt qmake generates makefiles with debug targets specified by default.

Is it possible to override this behavior? I just want to build release version of my app with 'qmake && make && make install'

Thank you.

the issue can be closed, qmake behavior is correct
