No, those are Makefile variables, not qmake ones. 

qmake writes them unconditionally:
    t << "QINSTALL      = " << var("QMAKE_QMAKE") << " -install qinstall" << 
endl;
    t << "QINSTALL_PROGRAM = " << var("QMAKE_QMAKE") << " -install qinstall -
exe" << endl;

The only way to override them is to trick qmake into adding something to the 
Makefile that it doesn't expect to. Needless to say, brittle and unsupported.
