Bug#322404: planner-el: makeinfo under en_US locale

package planner-el
retitle 322404 planner-el: makeinfo under LANG=C
thanks

I think make document under LANG=C is a standard process, for example,

$ apt-get source debian-policy
[snip]
$ cd debian-policy-3.6.2.1/
$ grep "LANG=C" Makefile
        LANG=C debiandoc2html $<
        LANG=C debiandoc2text $<
        LANG=C debiandoc2latexps $<
        LANG=C debiandoc2latexpdf $<
