    Re: PowerPC64 pcrel got relocs against local symbols
    
    The last patch wasn't all that shiny.  There are rather a lot more
    relocations that can hit the assertion in md_apply_fix if the symbol
    is local or absolute.  Fix them all.
    
            * config/tc-ppc.c (ppc_force_relocation): Add all relocs that
            expect a symbol in md_apply_fix.  Remove tls pcrel relocs
            already covered in general tls match range.
    
    (cherry picked from commit 8b168f1a1e09e337d2a970f204a0230c091bbe58)
