Built, with a randomly selected .config (that is, a .config I use for
other things, not a .config with the values set at random!)
Not quite built without problems. Can you guess the cause of this?

Guess where the static libutil.a is. That's right, /usr/lib. Are
we searching it in that linker script? No :(

Looks like a thread initialization problem to *me*. And there be very
serious and nasty snarling dragons with sharp pointy carborundum teeth
:(
(this box, btw, is an AMD Athlon 4: it *does* have CMOV support. Not
that that could plausibly be the problem here.)

Whoops!
I guess not many people have tried to build -bs6, then: I doubt that would work
terribly well in skas mode, either ;)

... I used these, which applied fine.

I guessed that. Merely .it is a preetty big clue. Myself, I've carefully
steered clear of southern Europe and points south in the summer. April
Rome temperatures are about the most I'm comfortable with.

Well, it's done that in the south-east of England, too, but I don't have
to like it, and it's `exceptional' (i.e. `has happened almost every year
for the last decade' :( )
