  20 *      We have the following to choose from:
  21 *        arm7          - ARM7 style
  22 *        v4_early      - ARMv4 without Thumb early abort handler
  23 *        v4t_late      - ARMv4 with Thumb late abort handler
  24 *        v4t_early     - ARMv4 with Thumb early abort handler
  25 *        v5t_early     - ARMv5 with Thumb early abort handler
  26 *        v5tj_early    - ARMv5 with Thumb and Java early abort handler
  27 *        xscale        - ARMv5 with Thumb with Xscale extensions
  28 *        v6_early      - ARMv6 generic early abort handler
  29 *        v7_early      - ARMv7 generic early abort handler
