bin_library_info.sh is a tool that create a unique filename for a binary tar file that
contain the build of the given source tarfile. the unicity is based on the source tarfile which contains
a md5 already and the calculated sha1 of config_host_.mk and of the tree object associated with the top_level_module
in git.
syntax: bin_library_info.sh -m|--module <top_level_module> -l|--location <TARFILE_LOCATION> -s|--srcdir <SRCDIR> -b <BUILDDIR> -r|--tarfile <LIBRARY_TARFILE> [ -m|--mode verify|name ]
the default mode is 'name' which just print the associated binary tarfile name.
in 'verify' mode the programe print the name if the associated binary tarfile exist
and print nothing and return an error code if the file does not exist
Note: --location --builddir and --srcdir are optional if they are already in the env in the form of TARFILE_LOCATION and BUILDDIR SRCDIR respectively
