# MRI scripts have a problem with +. It's a line contination character
# unfortunately there is no escape character. We know we don't have
# "+" in libraries or the MariaDB paths, but Ubuntu CI builds will have
# in their CI path due to the package names that Ubuntu generates.
# So here we replace the fully expanded paths in the TARGET_SCRIPT,
# strip off the TOP_DIR to make it a relative path to the top level directory
# and then execute AR on the top level directory.
