* readelf.c (byte_get_little_endian): Comment typo fix.

Browse Source 
(print_symbol): Constify "symbol" arg.  Don't pass "symbol" to printf
	as the format string.
	(dump_relocations): Correct section sym names.
	(process_section_headers): Clear symtab_shndx_hdr.
	(read_and_display_attr_value): Don't pass indirect string to printf
	as the format string.
	(display_debug_frames): Indicate when zero terminator found.  Decode
	DW_EH_PE_pcrel addresses.
