279ec488e3 bios: Print location jumping too. 
Makes it easier to  understand what is happening (and that the BIOS is
jumping to the right place).

b1b6a74170 or1k: Use EXCEPTION_STACK_SIZE of 256bytes. 
or1k defines a 128 byte "red zone" after the stack that can not be
touched by the exception handler.

We also need 128 bytes to store the 32 registers.

libbase: Adding missing vprintf function.

548fd33d20 libbase: Adding missing vprintf function. 
Fixes #8.

```
int vprintf(const char *format, va_list ap);

The functions vprintf(), vfprintf(), vsprintf(), vsnprintf() are equivalent to
the functions printf(), fprintf(), sprintf(), snprintf(), respectively, except
that  they  are  called  with  a  va_list instead of a variable number of
arguments.
```
