* som.c (som_reloc_skip): Correct off-by-one error for 4-byte 

R_NO_RELOCATION fixups.
	(bfd_section_from_som_symbol): Return the absolute section if the
	symbol isn't contained in any section in the output file.
	(som_slurp_symbol_table): ST_PRI_PROG and ST_SEC_PROG symbols are
	not function symbols (they are magic code labels which *can* be the
	targets of cross space branches).  $START$ is not a section symbol.
