[Bug 215819] head r311147's clang 3.9.1 for powerpc64: locore.o generation messed up: generates R_PPC64_ADDR16_DS instead of R_PPC64_TOC16_DS with .toc

The following locore64_simplified.S source code is sufficient to
show the silent R_PPC64_ADDR16_DS generation problem:

        .align  4
        .data
        .p2align 2
        .globl  tmpstk
        tmpstk:
        .space  16384

        .section ".toc","aw"
tmpstk.L: .tc tmpstk[TC],tmpstk

        .text
        ld      %r1,tmpstk.L(%r2)
