[PATCH 3/3] gcc/ada/socket.c: Add conditionals for RTEMS

[Joel Sherrill <joel dot sherrill at oarcorp dot com>]

This patch is needed to make Ada compile for *-*-rtems*
on GCC 4.8, 4.9, and the head. Is is ok to commit?

2014-08-11  Joel Sherrill <joel.sherrill@oarcorp.com>

	* socket.c: Add conditionals for RTEMS. Add include of <unistd.h>
	and so correct prototype of gethostbyname_r() is used.
