Subject: [PATCH] softfloat: Fix the default qNAN for target-ppc

Currently float128_default_nan() returns 0xFFFF800000000000 in the
higher double word, but it should return 0x7FFF800000000000 which
is the correct higher double word for default qNAN on PowerPC.

Backports commit 5d51eaea84899d88cb161fab3f089168e3812e9e from qemu
