How exactly? I have a .mk with:
$(MYPACKAGE_DIR)/.configured: $(MYPACKAGE_DIR)/.unpacked
        (cd $(MYPACKAGE_DIR); rm -rf Makefile; \
         $(QTOPIA4_QMAKE) -spec
qws/linux-$(BR2_PACKAGE_QTOPIA4_EMB_PLATFORM)-g++ \
        )
        touch $@

What should I change?

It worked for me as it was then. The executable on the target ran just fine.

AFAIK, makes the life of users of the lib easier, so they can call
qmake without having to know buildroot specific issues.
