powerpc: select endianness
This patch allows to build tests for ppc64 little endian target
(ppc64le) on big and little endian hosts.
We add a new parameter to configure to select the endianness of the
tests (--endian=little or --endian=big).
I have built and tested big and little endian tests on a little
endian host, a big endian host, with kvm_hv and kvm_pr, and on
x86_64 with ppc64 as a TCG target.
