Hi,

simple patch to improve the output of objdump --sym:
* common symbols are marked COM (instead of UND).
* Section name is displayed in brackets to make the output more readable.

Example:

0000000000000000 g       0f SECT   01 0000 [.text] _p13
0000000000000028 g       0f SECT   02 0000 [.eh_frame] _p13.eh
0000000000000004         01 COM    00 0200 _v20

	* mach-o.c (bfd_mach_o_print_symbol): Display COM for common
	symbols.  Print section name in brackets.
