Sadly:

     -n              Sorts external symbols by name  before  they
                     are printed.

and

     -r              Prepends the name  of  the  object  file  or
                     archive to each output line.

Reverses the sort order with GNU nm.

You set NM=gnm, so you should be okay with the GNUisms.
