Port _setjmp fix to POSIXish hosts as well as Microsoft.

* nt/config.nt: Attempt to sync with autogen/config.in.
(HAVE_SIGSETJMP, HAVE__SETJMP): New macros.
(_longjmp, _setjmp): Remove.
* src/image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
it's needed on POSIXish hosts that lack _setjmp.  Attempt to solve
the Microsoft problem in a different way, by altering nt/config.nt.
