* ltconfig.in: Reverted June 6's patch for new GNU ld output, it

is no longer needed, as ld reverted to the original format.
* NEWS: Likewise.

* ltconfig.in: When testing self-dlopening, test whether dlclose
crashes.  On FreeBSD 3.1, it does.  :-(
* libltdl/configure.in: Likewise.
* NEWS: Note work-around.
