Better indirect and warning symbol handling inspired by Stuart
Quick <stuck@cs.man.ac.uk>.
* linker.c (enum link_action): Add REF, MIND, CWARN, REFC.
(link_action): Change UNDEF_ROW/def and UNDEFW_ROW/def from NOACT
to REF. Change UNDEF_ROW/indr and UNDEFW_ROW/indr from CYCLE to
REFC. Change DEF_ROW/indr and COMMON_ROW/indr from CYCLE to MDEF.
Change DEFW_ROW/indr from CYCLE to NOACT. Change INDR_ROW/indr
from MDEF to MIND. Change INDR_ROW/warn from WARNC to CYCLE.
Change WARN_ROW/def and WARN_ROW/indr from MWARN to CWARN. Change
WARN_ROW/com from MWARN to WARN. Change WARN_ROW/warn from NOACT
to CYCLE. Change SET_ROW/warn from WARNC to CYCLE>
(_bfd_generic_link_add_one_symbol): Handle REF, MIND, CWARN and
REFC. If a new indirect symbol has been referenced, push the
reference down to the symbol it points to. FIx handling of WARN.
* aoutx.h (translate_from_native_sym_flags): If N_WARNING, don't
clobber e_type of next symbol.
(translate_to_native_sym_flags): Likewise.
(aout_link_write_symbols): Loop on bfd_link_hash_warning as well
as bfd_link_hash_indirect.
