I hoped to just get one, but I get two; I configure using

    ../build/configure --host=i386-unknown-linux --target=i386-unknown-linux ...

Not even, this is inside a 32bit VM.  I was hoping to build an x86
toolchain on x86_64, but after these problems I setup a 32bit VM

Maybe I should use

    --host=i686-pc-linux-gnu --target=i686-pc-linux-gnu

?

Hmm, this is definitely wrong.

I'll have a look at this first...
