I only tried to use either -meabi (this seems to be the default for this
powerpc-*-eabi -target) or -mno-eabi.

When I use the -mno-eabi, there is a different stack alignment but the
call to __eabi still insists being there. I guess I will have to look at the 
specs file. The older compiler version on the Linux box works differently
than this (=correcly) with the -mno-eabi.
