from native-1.2.11, so I've used that:

do_configure() {
        rm -f ${S}/acinclude.m4
        cp ${WORKDIR}/acinclude.m4 ${S}/
        gnu-configize
        oe_runconf
        cd ${S}
        # prevent libtool from linking libs against libstdc++, libgcc, ...
        cat ${TARGET_PREFIX}libtool | sed -e 's/postdeps=".*"/postdeps=""/' > ${TARGET_PREFIX}libtool.tmp
        mv ${TARGET_PREFIX}libtool.tmp ${TARGET_PREFIX}libtool
}

from x11-1.2.9, didn't work for me:

do_configure_prepend() {
        rm -f ${S}/acinclude.m4
        cp ${WORKDIR}/acinclude.m4 ${S}/
}

do_configure_append () {
        cd ${S}

        # prevent libtool from linking libs against libstdc++, libgcc, ...
        cat ${TARGET_PREFIX}libtool | sed -e 's/postdeps=".*"/postdeps=""/' > ${TARGET_PREFIX}libtool.tmp
        mv ${TARGET_PREFIX}libtool.tmp ${TARGET_PREFIX}libtool
}
