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.
