Do you have a testcase I can look at?  As far as I know, --relax still works.

This problem happens when you are calling a function that is too far away
for the offset in a br.call instruction.  Or jumping to a branch that is too
far away.  This could be a toolchain bug, or it could be a problem with the
program.

This was a temporary problem.  It occurs if you have a toolchain with Richard
Henderson's 2000-10-09 bfd patch for sorting unwind sections, but don't have
his 2000-10-24 bfd patch which makes it work.  I never released a toolchain
with the first patch but not the second.  Perhaps you got a toolchain from
someone else?  Or maybe you applied random patches from some mailing list
to your toolchain?

This is 2 months obsolete.  The 001117 snapshot should be used instead of this
one.
