PATCH: fix som_get_reloc_upper_bound if no reloc

[Tristan Gingold]

Hi,

this seems to be an obvious patch: if there are no relocs,  
bfd_get_reloc_upper_bound should returns
sizeof (arelent *) for the ending NULL (and not 0).

	* som.c (som_get_reloc_upper_bound): Returns sizeof (arelent *)
	instead of 0 if there are no relocs.
