* elfread.c (elf_symtab_read): Properly sort out the bss symbols

	* elfread.c (elf_symtab_read):  Properly sort out the bss symbols
	from the data symbols and give them the correct minimal_symbol_type.
	Add file static symbols to the minimal symbol table, not just
	global symbols.  Ignore symbols that are section names and file names.
	* dwarfread.c (add_partial_symbol):  Add comment about limitations
	of DWARF symbols for distinquishing data from bss when adding
	minimal symbols.  Add file local symbols to minimal symbols.
