  After updating to binutils 2.34.90.20200706-1ubuntu1 Linux' perf build
  is failing with the following error:

  
/usr/bin/ld:/tmp/autopkgtest.440kEd/build.N7g/src/debian/build/tools-perarch/tools/lib/traceevent/plugins/libtraceevent-dynamic-list:2:
 ignoring invalid character `@' in script
  
/usr/bin/ld:/tmp/autopkgtest.440kEd/build.N7g/src/debian/build/tools-perarch/tools/lib/traceevent/plugins/libtraceevent-dynamic-list:2:

/usr/bin/ld:/tmp/autopkgtest.440kEd/build.N7g/src/debian/build/tools-perarch/tools/lib/traceevent/plugins/libtraceevent-dynamic-list:2:
 syntax error in dynamic list
  collect2: error: ld returned 1 exit status

  The file mentioned in the error (libtraceevent-dynamic-list) contains
  some '@' that ld doesn't seem to like:

  $ cat lib/traceevent/plugins/libtraceevent-dynamic-list
  {
  __stack_chk_fail@@GLIBC_2.4;
  free@@GLIBC_2.2.5;
  memset@@GLIBC_2.2.5;
  realloc@@GLIBC_2.2.5;
  sprintf@@GLIBC_2.2.5;
  strcmp@@GLIBC_2.2.5;
  strdup@@GLIBC_2.2.5;
  strncmp@@GLIBC_2.2.5;

  tep_get_field_val;
  tep_is_file_bigendian;
  tep_is_local_bigendian;
  tep_plugin_add_options;
  tep_plugin_remove_options;
  tep_print_func_field;
  tep_print_num_field;
  tep_read_number_field;
  tep_register_comm;
  tep_register_event_handler;
  tep_register_print_function;

  tep_unregister_print_function;
  trace_seq_printf;
  trace_seq_putc;
  trace_seq_puts;
  trace_seq_terminate;
  warning;
  };

  The same file generated in a Focal environment (w/ binutils
  2.34-6ubuntu1) looks as following:

  $ cat lib/traceevent/plugins/libtraceevent-dynamic-list
  {
  __stack_chk_fail;
  free;
  memset;
  realloc;
  sprintf;
  strcmp;
  strdup;
  strncmp;
  tep_find_any_field;
  tep_find_field;
  tep_find_function;
  tep_find_function_address;
  tep_get_field_raw;
  tep_get_field_val;
  tep_is_file_bigendian;
  tep_is_local_bigendian;
  tep_plugin_add_options;
  tep_plugin_remove_options;
  tep_print_func_field;
  tep_print_num_field;
  tep_read_number_field;
  tep_register_comm;
  tep_register_event_handler;
  tep_register_print_function;
  tep_unregister_event_handler;
  tep_unregister_print_function;
  trace_seq_printf;
  trace_seq_putc;
  trace_seq_puts;
  trace_seq_terminate;
  warning;
  };

  And here is the chunk of Makefile that is generating this file:

  define do_generate_dynamic_list_file
  symbol_type=`$(NM) -u -D $1 | awk 'NF>1 {print $$1}' | \
  xargs echo "U w W" | tr 'w ' 'W\n' | sort -u | xargs echo`;\
  if [ "$$symbol_type" = "U W" ];then \
  (echo '{';  \
  $(NM) -u -D $1 | awk 'NF>1 {print "\t"$$2";"}' | sort -u;\
  echo '};';  \
  ) > $2; \
  else\
  (echo Either missing one of [$1] or bad version of $(NM)) 
1>&2;\
  fi

  My guess is that something changed in the output of `nm` to show the @
  charaters that ld does not like.

  This problem is currently breaking all kernel builds in Groovy.
