[RFC PATCH 3/3] Consolidate Linux sigprocmask() implementationa for alpha

[Yury Norov <ynorov at caviumnetworks dot com>]

Currently alpha port uses osf_sigprocmask to implement sigprocmask().
Minimal supported kernel version is 3.2, and it exposes rt_sigprocmask
system call for alpha. This RFC patch switches alpha to rt_sigprocmask,
similarly to other ports. If alpha community OK, please pull it.

	* sysdeps/unix/sysv/linux/alpha/sigprocmask.c: Consolidate
	sigprocmask() implementation.
