Marcel Moolenaar 294800e52d Make remote GDB work for AIM processors. For BookE, the kernel
will have a special section, named .PPC.EMB.apuinfo, which will
tell GDB that a BookE processor is targeted and which will
result in GDB using a different register definition. In order
to support remote GDB for BookE, we need the GDB stub in the
kernel look for that section and use the BookE definitions.
