 This happens because setuptools is called with:

	PYTHONPATH="/usr/lib/python$(PYTHON_VERSION_MAJOR)/site-packages"

 Yegor, Gustavo, any idea why this is called with a python path pointing
to the host? Maybe this isn't needed anymore? A quick grep in the source
doesn't indicate an obvious place where PYTHONPATH would be relevant
during install itself.

 I've just tried removing the PYTHONPATH override and it built OK, but I
haven't tested if a package installed with setuptools actually works.
Well, actually, host-setuptools _doesn't_ have that strange
PYTHONPATH override and that is of course the only one used within
buildroot itself...

 Arnout
