sys/linux: switch ppc64le to little-endian

make extract recently broke for powerpc on linux-next with:

include/uapi/linux/byteorder/big_endian.h:6:2: error: #error "Unsupported endianness, check your toolchain"
 #error "Unsupported endianness, check your toolchain"

Turns out we always built ppc64le headers as big-endian.
First, kernel was configured as BE.
Then, we used gcc to build an executable program for host
and on x86 gcc does not define __LITTLE_ENDIAN__ so kernel
thought that the toolchain is BE too.

Configure kernel as LE and define __LITTLE_ENDIAN__.

This actually changes values of some consts,
but fortunately just few of them.
