SMP support for Raspberry Pi 2

[Rohini Kulkarni]

Hi,

I am building with the --enable-smp option. But RTEMS_SMP is not getting
defined.
I have referred to the configure files of other BSPs which includes the
script for --enable-smp option and changed the configure script for
raspberry pi. What can be the reason, I am unable to understand what I am
missing.

Thanks.
