This is what I did in -RC4. I also added a check for "compiled against
1.0.0+, but running with older version" (which may happen with dynamic
linking). This is totally untested.
The warning message I added says it disables OpenMP, although it
actually only reduces max_keys_per_crypt to 1. This appears to have
almost no performance impact for this format, so I think it's OK as a
workaround (definitely better than a crash).

Is there a non-negligible number of systems running versions newer than
0.9.8o but not newer than 0.9.8r? I mean, enough for us to care to
enable OpenMP for SSH for (some of) those, if we can. Your time might
be better spent improving the code in other aspects first.
Thanks,
Alexander
