Hmm the python3-native recipe has this install function:

----------------------------------------------------------
do_install() {
        install -d ${D}${libdir}/pkgconfig
        oe_runmake 'DESTDIR=${D}' install
        if [ -e ${WORKDIR}/sitecustomize.py ]; then
                install -m 0644 ${WORKDIR}/sitecustomize.py
${D}/${libdir}/python${PYTHON_MAJMIN}
        fi
        install -d ${D}${bindir}/${PN}
        install -m 0755 Parser/pgen ${D}${bindir}/${PN}

        # Make sure we use /usr/bin/env python
        for PYTHSCRIPT in `grep -rIl ${bindir}/${PN}/python
${D}${bindir}/${PN}`; do
                sed -i -e '1s|^#!.*|#!/usr/bin/env python|' $PYTHSCRIPT
        done
}
----------------------------------------------------------


If I change the sed line to "#!/usr/bin/env python3", that would
probably work then. But would it break something else?
