This extension is not about DW_AT_linkage_name vs. DW_AT_MIPS_linkage_name.
It is about DW_AT_{,MIPS_}linkage_name for DW_TAG_structure_type which did not
have any meaning before.

The extension is used by GDB DWARF reader, more info at:
http://sourceware.org/ml/gdb-patches/2011-03/msg00916.html

It is just an earlier indication of how will be the DW_TAG_typedef DIE named
for an anonymous struct/class/union.

I do not know if it has anything to do with LTO inside GCC.  FYI this
DW_AT_{,MIPS_}linkage_name is fully qualified = already contains namespaces.
