I can reproduce this.

The only place in rtems.git which provides a symbol named __rtems_start
However, this file doesn't seem to be referenced by the mcp750 BSP nor
by the motorola_powerpc:
# grep -R shared/start/vectors_entry.S
Seems to me, as if some of the powerpc exception/irq "generalizations"
I am not sufficiently familiar with how this is supposed to work to be
able to provide a fix.
