This is The GCC Bug that I occasionally make reference to.  Basically,
GCC is generating relative branches too large.  The only way to fix
this is to have it calculate instruction lengths, and nobody has been
willing to devote the time to write the code for it.  (It does this on
other machines, like the 386, already.  I think the RS/6000 is the only
one that's broken.)

I'm not sure why you're getting that error compiling GCC itself though.

(BTW, in older version of the assembler, it would blindly assemble the
bad offset, truncating it.  This usually caused mysterious failures of
the resulting code.)
