[bug-unrtf] unrtf-0.21.0 build issues

[Nelson H. F. Beebe]

I attempted builds of unrtf-0.21.0 in 49 environments on about 25
flavors of Unix in my test lab, and ALL got universal failure.

With some experimentation, I found two root causes:

(1) The top-level Makefile does not have LIBS set: it needs to
    include -liconv.

    When I restarted the make with "make LIBS=-liconv", I got
    a successful link on one platform (presumably the others
    would work too after a similar step).

(2) Once unrtf is built, "make check" fails like this:

        Making check in tests
        ../src/unrtf ./Greek1.rtf > Greek1.rtf.html
        /usr/local/lib/unrtf/outputs/html: No such file or directory
        no config directories
        FAILURE!
        ...
        many more such

    I then did a "make install", and reran the "make check".  It then
    succeeded.

It is IMPERATIVE that a validation suite be runnable without
installing the software; otherwise, there is serious risk of (a)
installing something that doesn't work and (b) wiping out a
previously-working installation (in this case, of unrtf-0.20.5).

If you provide me a URL to grab an updated version of unrtf with
patches to fix these two problems, I'll be happy to give it a pretest
in my lab before it is announced further.  That way, installers should
have a better success rate.
