I am no expert in this, but I highly doubt that this is supposed to 
So far you only have a cross-compiler for RTEMS for the aarch64 target.
However, as ARMv8 is a new architecture for RTEMS I would expect that 
you need to first add support for this new architecture to the 
RTEMS-kernel and probably the configure scripts as well. I have never 
done this, so I can't help here. The RTEMS porting guide might be a 
first step in understanding what you have to do: 

Another thing is that you want to build the raspberrypi-bsp. I assume 
you want to build RTEMS for the raspberry pi 3. The new raspberry uses 
another cpu as the older versions and of a different target 
architecture. That means from the operating system's point of view it 
differs significantly from the older ones, thus you cannot expect that 
the bsp for the RPi 1 and RPi 2 will work for the RPi 3.
No one has added support for the RPi 3 yet. It's very new on the market 
and RTEMS has currently no ARMv8 support.
