Hi,
this is a tiny patch to fix the use of prologue_saves on avr6. As
EIND is always 0, a stub must be
generated (if required) for the return point.
Tested by recompiling GCC.
Tristan.

* config/avr/avr.md ("call_prologue_saves"): Use hi8(gs())/lo8(gs())
instead of pm_lo8/pm_hi8 to makes this call working on avr6.
