Can't cross compile texinfo

[ElvishJerricco]

@Mic92 I was trying to use your fork, but it failed to build because of texinfo.

  ../tools/info/makedoc ./session.c ./echo-area.c ./infodoc.c ./m-x.c ./indices.c ./nodemenu.c ./footnotes.c ./variables.c
  /nix/store/dkh7l9a4sx7zqh8riqbj3z21sz25p8xy-bash-4.4-p23/bin/bash: ../tools/info/makedoc: No such file or directory

I have not tried in a while, but this one definitely build fixed texinfo for me: Mic92/nixpkgs@0009bd7

texinfo succeeds, but texinfoInteractive fails. Interesting.

[Mic92]

There are more patches required to also built this.

[ElvishJerricco]

@Mic92 Were you ever able to build your fork? It ought to be depending on texinfoInteractive, which fails to build.

[Mic92]

I was able to build a raspberry pi image. It seemed to be not depend on texinfoInteractive at the time.

[ElvishJerricco]

@Mic92 running the command in your fork's README yields the texinfoInteractive build error, but that command should be reproducible. Was there some other variable?

[Mic92]

sorry don't know. Maybe there is a way to skip creating documentation from docstrings (?) for texinfo in the cross-compiling case.

This commit from @thefloweringash worked for me.
