[Qemu-devel] [PATCH] Sparc64 host support, PPC soft float

[Blue Swirl]

I converted PPC to use soft float instead of native FPU. I don't have much 
PPC software available, but at least some qemu-tests files work on an x86 
host.

As I also fixed the bug with system emulators not passing final link (in 
sparc64.ld), now all default user and softmmu targets can be built on a 
Sparc64 host.

The native FPU is still used for x86 targets, for example in fild and fadd. 
Sparc32/64 can't move stuff from integer registers to FPU directly, some 
memory buffer must be used in between. GCC allocates a stack frame for this, 
but due to bug in save instruction offset check in dyngen.c, it's not 
noticed. Maybe I'll fix these too.
