Previous implementation was just wrong lets face it.

This reverts commit 4ac86b03.

This is better idea as having #!/bin/bash -e is fragile. Anyone can run
this script with bash -x file and that way unintentionally disable -e
flag.

On server is currently used invalid configuration. This commit can be
reverted after merge to master and configuration file update.

Until now it was called somewhat not systematically before every build
and after OpenWRT patching.

This is code that was originally only in Jenkins but it makes sense to
have this prepare stage externally documented and git tracked so I moved
it here.

Empty make argument causes make to build default target. This commit
removes any empty arguments from make calls.

Build is not split to multiple steps and having one central statistics
does not make sense. Also this stat is tracked by external build system
tool (Jenkins).

This also introduces new argument: -jNUM
This is more comfortable way to specify number of parallel jobs.

In configure command there are two major changes. VERSION_REPO is now
set to new path path that is unfortunately board unspecific but as
only one makes sense in new repository arrangement. Second change is
that we no longer build image builder and SDK. Image builder does not
make sense for use. We use updater to build images (medkits). SDK is at
current state useless. It does not contain anything other then compiler,
libraries are missing.

Second change is primarily done because of next change that is going to
be splitting off compile command to few subcommands and making sure that
we build only packages not anything else.

This is more appropriate name as this script now only generates
packages not complete firmware.

This is true but updater now directly depends on those tools so there is
no need to mention it there.

Function it is commenting on is already gone.
