2020-06-05  Nelson Chu  <nelson.chu@sifive.com>

	* elfnn-riscv.c (riscv_merge_attributes): Add new boolean
	priv_may_conflict, in_priv_zero and out_priv_zero to decide
	whether the object can be linked according to it's priv
	attributes.  The object without any priv spec attributes can
	be linked with others.  If the first input object doesn't contain
	any priv attributes, then we need to copy the setting from the
	next input one.  Also report more detailed error messages to user.

	Extend pdp11-aout symbol table format to accommodate .stab
	symbols and implement correct handling of them.

	* pdp11.c (pdp11_external_nlist): Repurposed e_unused to e_desc.
	(N_STAB, is_stab): Needed new function is_stab to disambiguate
	normal vs. .stab symbol table type values, replacing N_STAB mask.
	(translate_from_native_sym_flags): Determine correct section for
	different .stab types.
	(translate_to_native_sym_flags): Leave .stab types intact.
	(translate_symbol_table): Error if symbol indicates overlay;
	store desc field from .stab symbols.
	(write_syms): Output desc field with symbol.
	(aout_link_check_ar_symbols): Skip .stab symbols.
	(aout_link_add_symbols): Correctly distinguish .stab symbols.

	(aout_link_write_symbols): Write 0 for desk and ovly fields;

	section and value; and copy desc and ovly fields from input symbol
	to output symbol.
