It seemed like it should be straightforward enough; here's a trivial,
naive one, testing only for presence and linking (no version recency, et
cetera). It seems to work in my environment, as far as detecting the
presence of the library and getting the flags added to subsequent
compilation checks in the configure run without breaking other configure
checks that were previously passing, but I'm not sure how to properly
validate such a thing.

I wasn't at all sure where in the test order to put this. As written it
needs to go after the pkg-config check, but I don't see any obvious
ordering of the checks to base a decision on beyond that.

I'm running a compile test of the result now, but I have no reason to
expect that it would fail even if this is somehow broken, so it's just a
level of sanity validation.

Feedback would be appreciated.
