Hi all,

Following up from adding Cortex-A17 support this patch adds a big.LITTLE 
option cortex-a17.cortex-a7.
Similar to the existing cortex-a15.cortex-a7 support we schedule for 
Cortex-A7 and make the other tuning
decisions as for Cortex-A17.

Tested arm-none-eabi.

Ok for trunk?

Thanks,
Kyrill

     * config/arm/arm-cores.def (cortex-a17.cortex-a7): New entry.
     * config/arm/arm-tables.opt: Regenerate.
     * config/arm/arm-tune.md: Regenerate.
     * config/arm/bpabi.h (BE8_LINK_SPEC): Add mcpu=cortex-a17.cortex-a7.
     * config/arm/t-aprofile: Add cortex-a17.cortex-a7 entry to
     MULTILIB_MATCHES.
