The POSIX specification defines a 'trap <action> EXIT' mechanism that is useful to perform clean-up actions in shell scripts. A trap has two main advantages over hand-crafted clean-up mechanisms: - It runs even if the process is terminated by a SIGTERM. - It runs even if the script stops due to a pipeline failure (set -e). Now we can make the script to stop immediately if a compilation error occurs, instead of letting it try to run an unexisting program. This change may appear to be overkill but Buildroot is an open source project and each piece of code is a potential learning tool for other developments. We must strive to provide good examples.
