[MiNT] 1.15.9 and MP

[Jo Even Skarstein <jo-even.skarstein@stryn.online.no>]

I installed 1.15.9 yesterday, it works fine except that
there's a lot of problems with MP and N.AES. AESSYS is often
killed because of a memory violation, this has never
happened before (although I didn't use 1.15.7 long enough
to test it with MP.). I also had similar problems with
MultiTOS (AES 4.1).
