Note: The directory name for the generated debug version is still wrong.

in maschine.sh no modules are loaded and no env variables are set,
this breaks in case cmake is called later from make. Instead machine specific
config files are copied.

Added debug option to configure script
TODO:
ELPA version on JURECA can not be used. Interface of ELPA is changed :-(

configure.sh script is doing part of the job now
more details should be found in README (later :-) )
