Ok, I'll remove, I thought it would be ok because I fired up:

  # dnf install udis86-devel

On fedora and it installed straight away, but after I started trying to
update my docker images I couldn't find it on debian
experimental/unstable:

  [root@jouet ~]# docker run -t -i debian:experimental /bin/bash
  root@b97e620820b4:/# apt-get update

Nor even in OpenSuSE:

Or even Mageia:

[root@cb6ee54f2faa /]# urpmf udis86
    http://mirrors.ustc.edu.cn/mageia/distrib/5/x86_64/media/core/release/media_info/20150615-211931-files.xml.lzma

[root@cb6ee54f2faa /]#

But then, use in perf could be a driver for that package to get
included, perhaps we can do the same we did for libbabeltrace? I.e.
leave it disabled by default?

Thanks,
