I don't want to start a dispute, just to make sure my intent is clear.

We are calling `abort' here with a very specific purpose: producing a
core file.  On systems that don't support core files, calling `abort'
in this context does not make sense, even though `bort' is an ANSI
function and should be supported by any system where GDB can be built.
So the code which does that should not be compiled on such systems,
IMO.  Ifdef'ing it away conditioned by such systems is much easier
than introducing configury, whose results we know in advance.
