Now I understand a little bit more. I installed it into
PTXCONF_SYSROOT_TARGET because CROSS_PYTHON has the default
site-packages search path there.
I know this was wrong because it is a host tool which should installed
into PTXCONF_SYSROOT_HOST. I always search a way to change the default
site-packages search path and now I found it! [1]
Your solution to install it into HOST_CYTHON_PKGDIR will install Cython
into PTXCONF_SYSROOT_HOST which is correct, but then it doesn't work out
of the box, because CROSS_PYTHON doesn't search in PTXCONF_SYSROOT_HOST.
With solution of [1] I can change the site-packages search path with:
"$(CROSS_ENV) PYTHONUSERBASE=$(PTXCONF_SYSROOT_HOST) $(CROSS_PYTHON)"
and then it works with a installed Cython in PTXCONF_SYSROOT_HOST.
Please let me know if this is okay for you, maybe we can put this into
the default $(CROSS_PYTHON) path. It seems Cython is some special thing,
we need it only at compiletime and it have some cross compiled things in
there. I don't know what happens if we set PYTHONUSERBASE and python
uses still his default site-packages path or not.
