Warnings while building OpenJDK 8 on Linux

And looks, like this manual -
https://java.net/projects/adoptopenjdk/pages/Build#Fedora - help me with
that. It still building, but I'm already bypass compiling part, its
creating javadocs, or something like this, so I hope, that it builds well.

Probably it's good idea, to mark this section about building not only with
Fedora, but also with Arch Linux, or any bleeding edge Linux distro.
For Arch Linux, I could provide commands how to install stuff (replace yum
with pacman )

Konstantin.
