Use DW_AT_MIPS_linkage_name when available in vardie_from_symtable.

If there is a DW_AT_MIPS_linkage_name it encodes the actual name of
the variable as used in the symbol table.

* dwflpp.cpp (vardie_from_symtable): Check whether there is a
  DW_AT_MIPS_linkage_name attribute and use its value if so.
