"relocation truncated"

I wrote to Hohmuth about this, but he might be away or busy ...

  [v0.5 981012] Build problem when building oskit/examples/multiboot-smp:
  "relocation truncated" 
   I cannot reproduce this problem. However, as this binary isn't needed,
  you can work around this problem by "touch
  oskit/examples/multiboot-smp". (hohmuth 98/10/24)

I got exactly this error when I tried building Fiasco.

It was preceded by a warning coming from boot.S, which might be
connected, so I'm copying the edited highlights below.

Does anyone with knowledge of x86 assembler understand this problem,
and can they fix it?

How come it only affects some people? Is it caused by different
versions of the assembler? Isn't the assembler part of gcc? I'm using
standard gcc 2.7.2.3, so which other packages should I check the
versions of? I'm using Debian's binutils version 2.9.1.0.19a-2, for
example, as released with Debian 2.1.

I got the same assembler warning several times when building L4-Linux.
