Thank you H.J. I can confirm the patch works:

Before:

$ cat x.c
int nm_test_var;
int nm_test_var2 = 1234;

extern int foo (void);

int
main ()
{
  return foo ();
}

$ gcc-9 -fno-common x.c -c -flto && nm x.o
         U foo
00000000 T main
00000000 T nm_test_var
00000000 T nm_test_var2

After:
$ ~/bin/binutils/bin/nm --plugin
/usr/bin/../bin/../lib/bfd-plugins/liblto_plugin.so.0.0.0 x.o
         U foo
00000000 T main
00000000 B nm_test_var
00000000 D nm_test_var2
