[PATCH 1/3, libgomp]: Change gomp_futex_{wait,wake} to int

[Uros Bizjak]

2015-05-27  Uros Bizjak  <ubizjak@gmail.com>

    * config/linux/wait.h (gomp_futex_wait, gomp_futex_wake):
    Declare as int.
    (FUTEX_PRIVATE_FLAG): Remove L suffix.
    * config/linux/mutex.c (gomp_futex_wait, gomp_futex_wake):
    Declare as int.

Tested on x86_64-linux-gnu {,-m32}.

OK for mainline?

Uros.
