First, SPE has not been maintained and little participation from
Freescale.  I would rather deprecate all SPE support.  SPE ABI is
broken by design.

I find the approach very heavy-handed.  If you want to enable the
target hook for SPE *only*, that's fine with me.  The description and
references to prior SPE prologue and epilogue changes do not confirm a
wider problem.
