 inline assembly "jsr" is too wide

Hi Alexander,

I believe that this all can be traced to simple fault in the h8300.h 
header file which is allowing an extended version of the JSR instruction 
to be used for non H8300SX processors.  Please could you try out the 
attached patch and let me know if it solves the problem for you.

Cheers
