The original text was little bit cryptic and wasn't true in the end
because master is now considered v6.0 and this of course changes as we
go trough new versions. This should now explain reader how to get
specific version in more general terms.

gcc-multilib is required on host for compiling luajit.
If it is not installed, luajit fails with this error:

fatal error: bits/libc-header-start.h: No such file or directory

We use Luajit for Knot Resolver, Suricata.

Add TIP and remove the section with make menuconfig as it is no longer
necessary

It may contain some errors, needs to be tested, wrote it down from memory
without testing.

Commiting basic building script. Some functionality is already there, what is
missing is handling branches and freezing stuff, correct version setup (no need
in development for now), userlist generation and medkit creation (no need till
we build at least a big part of packages).
