This is related to the issue originally reported in LP Bug 1626269. Because Bug 1626269 references two distictly different problems, we are mirroring this over to track the issues with the missing crc32c module so that LP Bug 1626269 (IBM Bug 146571) can focus on the issue with the makedumpfile utility.
