This patch splits i386 out of the main Linux kernel-features.h.

Tested x86 that there are no changes to disassembly of installed
shared libraries.

	* sysdeps/unix/sysv/linux/i386/kernel-features.h: New file.
	* sysdeps/unix/sysv/linux/kernel-features.h [__i386__]
	(__ASSUME_SOCKETCALL): Do not define.
	[__LINUX_KERNEL_VERSION >= 0x020621 && __i386__]
	(__ASSUME_RECVMMSG_SYSCALL): Likewise.
	[__i386__] (__ASSUME_RECVMMSG_SYSCALL_WITH_SOCKETCALL): Likewise.
	[__LINUX_KERNEL_VERSION >= 0x030000 && __i386__]
	(__ASSUME_SENDMMSG_SYSCALL): Likewise.
	[__i386__] (__ASSUME_SENDMMSG_SYSCALL_WITH_SOCKETCALL): Likewise.
