You can only have floating point tasks if CPU_HARDWARE_FP or CPU_SOFTWARE_FP is true.  In this case you need a non-zero Context_Control_fp, since otherwise the context allocation in _Thread_Initialize() return NULL.

This is actually a workaround.  We should separate the floating point task property from the context, but this is another issue.
