make the ARM EABI the default ABI on arm, armeb, armv6 and armv6eb. This is intended to be the default ABI from now on with the old ABI to be retired. Because of this all users are strongly suggested to upgrade to the ARM EABI. As the two ABIs are incompatible it is unlikely upgrading in place will work. Users should perform a full backup and either use an external machine to upgrade, or install to an alternative location on their media. They should also reinstall all ports or packages when these are available. The only known issues are: - pkg incorrectly detects the ABI. This is fixed upstream, and will a patch will be made to the port. - GDB can have issues with executables built with clang. __FreeBSD_version has been bumped.
