Looking at the sources, opcode/ppc-opc.c, I see that the mtsprg macro
only takes 2-bit sprg register numbers, which is apparently correct for
the basic ppc architecture, but not for e500.  This should probably be
conditional on the architecture choice.  I haven't looked at any
architecture or processor manuals to double check.

Meanwhile, "mtsprg7 %r3" will work.  Likewise for mfsprg.
