I confirmed these, and compared the v2 patch set to the v1 patch set for
all the patches I'd already approved, and have reviewed the remaining
patches and reviewed those too, so you should be all set here.

The only bit left is that the MXFAST tunable definition is still left in
elf/dl-tunables.list but (1) I see no harm in that, (2) it helps with
ABI compatiblility between ld-linux and libc, and (3) I can't think of a
three.  We can remove it later if it's problematic.
