[PATCH, committed] Remove useless casts

[Steve Ellcey]

Yury,

Since your patch

https://sourceware.org/ml/libc-alpha/2016-09/msg00086.html

was approved a while back and since you don't have write access I have
gone ahead and checked it in for you. Â I double checked that it still
applied to the top-of-tree sources and that it did not cause any
regressions on aarch64 or x86 as well.
