PATCH: Add x32 support to sysdeps/x86_64/dl-tlsdesc.h

[Roland McGrath]

I think the bit using the union warrants a comment explaining why it's there.

Missing space before paren.

With those nits fixed, I'm happy with the change.
But I'd be happier yet if other people gave opinions
about the union trick vs explicit #ifdef's padding fields.


Thanks,
Roland
