  Now that the MicroBlaze 3.15 kernel has the pselect6, preadv and
pwritev syscalls, this patch updates kernel-features.h so they are
assumed to be present for 3.15 and later kernels.

Not tested.

	* sysdeps/unix/sysv/linux/microblaze/kernel-features.h
	[__LINUX_KERNEL_VERSION >= 0x030f00] (__ASSUME_PSELECT): Do not
	undefine.
	[__LINUX_KERNEL_VERSION >= 0x030f00] (__ASSUME_PREADV): Likewise.
	[__LINUX_KERNEL_VERSION >= 0x030f00] (__ASSUME_PWRITEV): Likewise.
