spapr/rtas: Force big endian compile for rtas 



At the moment the rtas's Makefile uses generic QEMU rules which means
that when QEMU is compiled on a little endian system, the spapr-rtas.bin
is compiled as little endian too which is incorrect as it is always
executed in big endian mode.

This enforces -mbig by defining %.o:%.S rule as spapr-rtas.bin is
a standalone guest binary which should not depend on QEMU flags anyway.
