    [GOLD] Symbol flag for PowerPC64 localentry:0 tracking

    This patch provides a flag for PowerPC64 ELFv2 use in class Symbol,
    and modifies Sized_target::resolve to return whether the symbol has
    been resolved.  If not, normal processing continues.  I use this for
    PowerPC64 ELFv2 to keep track of whether a symbol has any definition
    with non-zero localentry, in order to disable --plt-localentry for
    that symbol.

        PR 21847
        * powerpc.cc (Target_powerpc::is_elfv2_localentry0): Test
        non_zero_localentry.
        (Target_powerpc::resolve): New function.
        (powerpc_info): Set has_resolve for 64-bit.
        * target.h (Sized_target::resolve): Return bool.
        * resolve.cc (Symbol_table::resolve): Continue with normal
        processing when target resolve returns false.
        * symtab.h (Symbol::non_zero_localentry, set_non_zero_localentry):
        New accessors.
        (Symbol::non_zero_localentry_): New flag bit.
        * symtab.cc (Symbol::init_fields): Init non_zero_localentry_.
