Comment:
This error exists because `texinfo` is not added to the package definition as a build dependency. You will also get a second error when you add it. And this is because `texinfo`'s input encoding now UTF-8 by default and `m4.texi`'s not. You can solve this problem add `pre_build` section like this.

`pre_build() {
     sed -i '1 i @documentencoding ISO-8859-1' doc/m4.texi
}`
