/* This port was written assuming that pxCurrentTCBs always exists and that, in
single-core FreeRTOS, it would just have simply one element. That is not the
case in v11 - in single-core FreeRTOS the symbol pxCurrentTCB is defined
instead. This breaks this port in a number of ways. A quick solution is to
define pxCurrentTCBs here - it simply needs to be a pointer to pxCurrentTCB.
We will actually populate this pointer in the RTOS kernel entry function.
