Improve the portability of checksum calculations
The -a option of cksum is not widely supported. Unfortunately, there is
no standard way to calculate an SHA512 checksum. This commit adds a
sha512.sh script that calculates it using the sha512sum, shasum, or
sha512 utility, depending on which one is available on the system.
