ee600be6a6 ppc: fix crash in ppc system single step support 
There was a bogus case where two system debug ops get generated.  This
patch removes the broken system debug op. This was a left over after
making some changes to correctly generate debug ops on branch
operations inside gen_goto_tb();

The test case against this patch is to turn on single stepping with
timers, boot a linux kernel, set a breakpoint a do_fork and in gdb
execute "si 3000".  Then qemu-system-ppc will fault executing a debug
op, which should not have been executed.

e755699dc7 Always enable precise emulation when softfloat is used 
The patch below changes the way to enable softfloat on the PPC target. It
is now enabled when softfloat is used. The rationale behind this change
is that persons who want precise emulation prefer precision over emulation
speed.
