    PowerPC64 pcrel got relocs against local symbols
    
    Not that anyone would want to indirect via the GOT when an address can
    be loaded directly with pla, the following:
    
     pld 3,x@got@pcrel
    x:
    
    leads to "Internal error in md_apply_fix", because the generic parts
    of assembler fixup handling convert the fx_pcrel fixup to one without
    a symbol.  Stop that happening.
    
            * config/tc-ppc.c (ppc_force_relocation): Add PLT_PCREL34 and
            assorted GOT_PCREL34 relocs.
    
    (cherry picked from commit 49c3ed081fed6b8e2b48fdc48f805f11e4589514)
