If anyone has any objections, please let me know. ------------------ From: Ricardo B. Marliere commit a4e17a8f239a545c463f8ec27db4ed6e74b31841 upstream. In the case of a test that uses the special option ${KERNEL_VERSION} in one of its settings but has no configuration available in ${OUTPUT_DIR}, for example if it's a new empty directory, then the `make kernelrelease` call will fail and the subroutine will chomp an empty string, silently. Fix that by adding an empty configuration and retrying.
