nm handling of synthetic symbols

[Alan Modra <amodra at gmail dot com>]

Symbol sorting means we can't assume that the last n symbols are
synthetic.

	* nm.c (print_symbol): Remove is_synthetic param.  Test sym->flags
	instead.
	(print_size_symbols, print_symbols): Adjust to suit, deleting
	now unused synth_count param and fromsynth var.
	(display_rel_file): Adjust, localizing synth_count.
