Aurelien Jarno 8e7a6db965 target-ppc: fix nego and subf*o instructions 
The overflow computation of nego and subf*o instructions has been broken
in commit ffe30937. Contrary to other targets, the instruction is subtract
from an not subtract on PowerPC.

This patch fixes the issue by using the correct argument in the xor
computation. Thanks to Peter Maydell for the hint.

With this change the PPC emulation passes the Gwenole Beauchesne
testsuite again.
