arm: Split BE/LE abilist
The fix for BZ#18231 requires new symbols only for armeb. This patch adds the required folder and files for both BE and LE abilist. No semantic changes are expected. Checked with check-abi for arm-linux-gnueabihf and armeb-linux-gnueabihf. * sysdeps/arm/preconfigure.ac: Set machine based on endianness. * sysdeps/arm/preconfigure: Regenerate. * sysdeps/arm/be/Implies: New file. * sysdeps/arm/be/armv6/Implies: Likewise. * sysdeps/arm/be/armv6t2/Implies: Likewise. * sysdeps/arm/be/armv7/Implies: Likewise. * sysdeps/arm/le/Implies: Likewise. * sysdeps/unix/sysv/linux/arm/be/Implies: Likewise. * sysdeps/unix/sysv/linux/arm/le/Implies: Likewise. * sysdeps/unix/sysv/linux/arm/*.abilist: Move to sysdeps/unix/sysv/linux/arm/le/*.abilist. * sysdeps/unix/sysv/linux/arm/be/l*.abilist: New files.
