Ok, turns out to be a limitation of sed. The problem arrises in
the following libtool section:

  # Now compile the dynamic symbol file.
  $show "(cd $output_objdir && $CC -c$no_builtin_flag$pic_flag_for_symtable \"$dlsyms\")"
  $run eval '(cd $output_objdir && $CC -c$no_builtin_flag$pic_flag_for_symtable "$dlsyms")' || exit $?

  # Clean up the generated files.
  $show "$rm $output_objdir/$dlsyms $nlist ${nlist}S ${nlist}T"
  $run $rm "$output_objdir/$dlsyms" "$nlist" "${nlist}S" "${nlist}T"

  # Transform the symbol file into the correct name.
  compile_command=`$echo "X$compile_command" | $Xsed -e "s%@SYMFILE@%$output_objdir/${outputname}S.${objext}%"`
  finalize_command=`$echo "X$finalize_command" | $Xsed -e "s%@SYMFILE@%$output_objdir/${outputname}S.${objext}%"`
  ;;

I get:
  Output line too long.
  Output line too long.

for the assignment to compile_command.

I created a /bin/sh script that made only the assignment to
compile_command and duplicated the failure. Using GNU sed worked fine
with my sample script.
