[PATCH] AIX TLS DWARF symbols

[David Edelsohn via Gcc-patches]

    GCC currently emits TLS relocation decorations on symbols in DWARF sections.
    Recent changes to the AIX linker cause it to reject such symbols.
    This patch removes the decorations (@ie, @le, @m) and emit only the
    qualified symbol name.

Bootstrapped on powerpc-ibm-aix7.3.2.0.

            * config/rs6000/rs6000.c (rs6000_output_dwarf_dtprel): Do not add
            XCOFF TLS reloc decorations.
