Re: (ITS#7160) MDB-back is not buildable on HP-UX 11.31

Fixed in Git master.  Please test:

Also fixed contrib/ldaptcl which had the same bug.

POSIX 'make' does not specify '$<' for target rules (rules that
name an explicit target), only for inference rules:

Maybe because $< would be ambiguous in target rules with several
dependencies.  GNU 'make' defines it as the 1st dependency.
