DESCRIPTION="
ARM v6, little endian, EABI with vector floating point (vfp).

The Pentium II of the ARM world: this architecture was introduced in 2001
and actually shipped silicon around 2003.  This hardware can still run v4
and v5 instruction sets, but recompiling for armv6 should provide a
slight performance boost (and thus better battery life).
