make install step fails

Hi,

When I tried to build neovim with your docker file, the make install step fails at the last moment when trying to generate the helptags.

-- Generating helptags in /usr/local/share/nvim/runtime/doc.
CMake Error at /nvim/cmake/GenerateHelptags.cmake:25 (message):
  Generating helptags failed: - Segmentation fault
Call Stack (most recent call first):
  cmake_install.cmake:516 (INCLUDE)

Not life and death. I'm on Ubuntu 14.04 with Docker version 1.5.0, build a8a31ef. I thought maybe it was to do with the helptags generation being done through neovim and neovim requiring a tty or some such thing and it failing as that isn't available in the build process. I've got no idea about these things though.

No pressure, just thought I'd make a note!

@michaeljones I think they something changed in neovim, so it become failing. Sad, but have no time to look at it.

This has been reported in neovim/neovim#2364. Hopefully it will be resolved.
