The recent buserr handler cleanup in the Amiga locore.s made the label

Browse Source 
_buserr point to the 68020/030 buserr code _only_. This has broken access
error handling in the 060 support code.
This is repaired by jumping to _buserr60 from the 060SP, and by providing
a _buserr60 label identical to the _buserr in the unchanged m68k ports
using the 68060.
