ppc/ppc64: Compile purgatory code with gcc option -msoft-float
Recently we faced an issue on power7 machine where kernel hanged in purgatory.
Some investigation revealed that gcc is generating hardware FPU instructions.
I have been told we can't use it at this point of time and as kernel is
compiled with -msoft-float for ppc/ppc64, so should be purgatory (as it runs
inside kernel context).
Thanks to Jakub Jelinek and Lingzhu Xiang for debugging and coming up with
a fix for this issue.
