[rfc] [2/4] SPU overlay support: The SPU target part

[Emi SUZUKI]

Hello Ulrich, 

I know that the duscussion about the corresponding gdbarch changes is
going on (and I unfortunately have no alternative idea about it), but
just want to notice you something that I came across.

It will cause SEGV if objfile is NULL.  
That code seems to be optimized out by `-O2' option of GCC, though.
