The vrc4373 doesn't implement the "standard" virtual vector support. What
you are seeing is an oversight that the hal_ctrl_isr* functions in
hal/common were not sufficiently conditionally compiled, which I will fix.
[ Jesper, I will make these functions conditional on
CYGSEM_HAL_VIRTUAL_VECTOR_SUPPORT ]

To implement redboot you would need to implement virtual vectors for the
vrc4373 platform. There are plenty of examples in other platforms.
