The -c option expects a digest file in either BSD or coreutils format.
The output for matched and mismatched files is identical to that
of the coreutils version.
The review of these changes included test cases that have already
been committed for the functionality that existed before.
Another test script is added to cover the coreutils compatible
extension implemented by this patch.
This commit contains a tests/Makefile that has been cleaned up
compared to the review version, using an implicit rule to apply the
TESTBASE path at build time (and the scripts have been renamed to
have an extension of .SH instead of .sh to trigger this rule).

While the correctness of the supported hash algorithms can be tested
with the built-in self-test feature, these test cases are meant to
detect changes in the output format.
A follow-up commit will improve the compatibility with the coreutils
versions of the hash programs, and these tests should detect any
unintended side-effects of such a change on existing functionality.
