Using the python method 'cpu_count()' is not working everywhere.
In Linux containers, 'multiprocessing.cpu_count()' returns the number
of cpu's of the host machine, not the number assigned to the linux
container.
Summary:
So far, the build process was configured for each job individually. This
was flexible in the past, when frequent changes were needed. Now, since
the CI build configurations are very stable, it is huge effort to keep
the jobs aligned during changes (e.g. Qt upgrade, build arguments etc).
This, plus the need to version control the build process has driven
the creation of this build script. The script is running on all nodes
and provides a small number of arguments to configure the build.
Python script for creating symbols is incorporated and therefore renamed.

Runs dump_syms on each debug info file specified on the command line,
then places the resulting symbol file in the proper directory
structure in the symbol store path.
