	* adaint.c, adaint.h (__gnat_cpu_alloc, __gnat_cpu_alloc_size,
	__gnat_cpu_set_free): Create these wrappers around the CPU_ALLOC,
	CPU_ALLOC_SIZE and CPU_FREE linux macros.
	(__gnat_cpu_zero, __gnat_cpu_set): Use the CPU_ZERO_S and
	CPU_SET_S respectively because we are now using dynamically allocated
	CPU sets which are more portable across different glibc versions.
	* s-osinte-linux.ads (cpu_set_t_ptr, CPU_ALLOC, CPU_ALLOC_SIZE,
	CPU_FREE): Add this type and subprograms to be able to create cpu_set_t
	masks dynamically according to the number of processors in the target
	platform.
	(CPU_ZERO, CPU_SET): They are now mapped to the CPU_ZERO_S and CPU_SET_S
	respectively, so we need to pass the size of the masks as
	parameters.
	* s-taprop-linux.adb (Create_Task, Set_Task_Affinity): Use dynamically
	created cpu_set_t masks
	with the number of processors available in the target platform,
	instead of static bit arrays. It enhances portability because
	it uses the information from the target platform.
	* sem_ch8.adb: (Attribute_Renaming): When checking whether we
	are using a restricted run-time library, use the flag
	Configurable_Run_Time_Mode instead of Restricted_Profile.
