Fix __ASSUME_MLOCK2 for ARM, MicroBlaze (bug 23867).
The generic kernel-features.h defines __ASSUME_MLOCK2 for 4.4 and later kernels. However, for 32-bit ARM binaries running on 64-bit ARM kernels, and for MicroBlaze, the syscall was only wired up in the 4.7 kernel. (32-bit ARM kernels did have the syscall from 4.4 onwards.) This patch duly arranges for the macro to be undefined for those architectures for kernels before 4.7. Tested with build-many-glibcs.py for its ARM and MicroBlaze configurations. [BZ #23867] * sysdeps/unix/sysv/linux/arm/kernel-features.h [__LINUX_KERNEL_VERSION < 0x040700] (__ASSUME_MLOCK2): Undefine. * sysdeps/unix/sysv/linux/microblaze/kernel-features.h [__LINUX_KERNEL_VERSION < 0x040700] (__ASSUME_MLOCK2): Undefine.
