[OE-core] [CONSOLIDATED PULL 26/35] python: Fix build failure of python-elementtree on x86_64

[Saul Wold]

From: Khem Raj <raj.khem at gmail.com>

The problem is due to mixing of headers from host system
thusly corrected in setup.py by checkinng if we are cross
compiling

+when building python for qemux86-64 on ubuntu 11.10/64bit
+it gropes into host includes and then mixes them with cross
+includes and as a result some modules fail to compile and link
+one of the modules is python-elementtree which is then not
+found during image creation
+
+Proble is that setup.py tries to add native includes that newer
+ubuntu has introduced for multiarch support. But that should
+only happen for native builds and not cross building python
+so we add a check here.
