Remove kernel-features.h conditionals on pre-3.2 kernels.
This patch follows up on the increase in minimum kernel version by removing conditionals in non-x86, non-x86_64 kernel-features.h headers that are now constant for all supported kernel versions. * sysdeps/unix/sysv/linux/alpha/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x020621]: Make code unconditional. [__LINUX_KERNEL_VERSION >= 0x030200]: Likewise. [__LINUX_KERNEL_VERSION < 0x020621]: Remove conditional code. * sysdeps/unix/sysv/linux/arm/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x020621]: Make code unconditional. [__LINUX_KERNEL_VERSION >= 0x020624]: Likewise. [__LINUX_KERNEL_VERSION >= 0x030000]: Likewise. * sysdeps/unix/sysv/linux/hppa/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x020622]: Likewise. [__LINUX_KERNEL_VERSION >= 0x030100]: Likewise. [__LINUX_KERNEL_VERSION < 0x020625]: Remove conditional code. * sysdeps/unix/sysv/linux/ia64/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x020621]: Make code unconditional. [__LINUX_KERNEL_VERSION >= 0x030000]: Likewise. * sysdeps/unix/sysv/linux/m68k/kernel-features.h [__LINUX_KERNEL_VERSION < 0x030000]: Remove conditional code. * sysdeps/unix/sysv/linux/microblaze/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x020621]: Make code unconditional. [__LINUX_KERNEL_VERSION < 0x020621]: Remove conditional code.

[_MIPS_SIM == _ABIN32 && __LINUX_KERNEL_VERSION < 0x020623]: Remove conditional code. * sysdeps/unix/sysv/linux/powerpc/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x020625]: Make code unconditional. [__LINUX_KERNEL_VERSION >= 0x030000]: Likewise. * sysdeps/unix/sysv/linux/sh/kernel-features.h [__LINUX_KERNEL_VERSION >= 0x020625]: Likewise. [__LINUX_KERNEL_VERSION >= 0x030000]: Likewise.
