This is my preferred solution, and is hopefully only a temporary one.  However, I know David Faure doesn't like it, and (I assume) would rather have a generic LIBEXEC variable.

My view is that libexec should be used for stuff that's really internal to a piece of software (like a framework), and so a libexec env var shouldn't be necessary (except maybe for relocatability?), but the current situation with drkonqi should hopefully be a temporary one (until 5.1 or something), and so a specific var for unusual situations is reasonable.

However, given that an objection has already been raised by the maintainer, I'm not willing to give it a ship-it without his agreement.
