[PATCH] _LINUX_TYPES_H redefinition warnings.

[Carlos O'Donell]

libc-alpha,

Should _LINUX_TYPES_H be defined to 1, or rather just defined.
It seems that legacy has been to just define the name without a value.
This patch will produce a build with less redefinition warnings under hppa.

	* sysdeps/unix/sysv/linux/sys/sysctl.h:
	(_LINUX_TYPES_H): Add conditional define.
