Log Message:
__mcount() relies on a standard m68k stack frame and the frame pointer for
two things:

1- return address in __mcount()'s frame is used to get selfpc (i.e. the
   function being instrumented).

2- __mcount() uses the saved-%fp in its own frame to get the frame pointer
   of the instrumented function, which is then used to get return address
   in that frame in order to get frompc.

Ensure __mcount()'s stack frame is always set up correctly by decorating
wiht __attribute__((__optimize__("no-omit-frame-pointer"))).
