Thank you for the report and the patch.
However, there are plenty of systems for which base64 --decode would
not work either, so I've done this, which should work on a superset:

    tests: avoid unnecessary "skip" without base64 -d support

    * tests/pcre-jitstack: Try harder to find a base64 decoder:
    Try 'base64 -d', 'base64 -D', 'openssl base64 -d' and perl's
    MIME::Base64 decode_base64.  The old code would skip at least on
    OS X, for which base64 expects -D or --decode.
    Reported by Jack Howarth in http://bugs.gnu.org/24243.
