Review comment:
if _svectors is changed to:
extern up_vector_t _svectors;
compiler will assume _svectors has only one element, and report the out of
range:
```
c5471/c5471_irq.c: Fix error: '__builtin_memcpy' forming offset [4, 31] is
out of the bounds [0, 4] of object '_svectors' with type 'int'
```
