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.

Merge branch 'ppc64/initial-drop-v7' of https://github.com/rhdrjones/kvm-unit-tests into HEAD

This series brings basic setup; starts a test's C entry point, main(),
and printf, exit, and malloc work. Three more series should follow this
one which must bring; vector support, mmu support, and smp support, at
which point I believe the framework could just evolve with the creation
of unit tests.

Tested on TCG and a P8 kvm_pr machine, and Laurent has tested it on
both a PowerMac G5 (kvm_pr) and a kvm_hv machine. I'm looking forward
to hearing more testing feedback from others though.

Use the arm/arm64 framework as a template to start a skeleton

verbatim. We'll modify them for powerpc with the next patch,
making it clear what needs to be changed.
