Issue when host-python3 is built before crda. The easiest solution is
probably to make the crda Python script Python 3 compatible and submit
the patch upstream.

Parallel installation issue with Python 3. Either we should make Python
3 entirely use MAKE1, or fix the problem. I have analyzed the problem,
and it is caused by the parallel installation of libpython into the
HOST_DIR and the execution of ./python in the Python source directory.

Scons is not compatible with Python 3. But host-scons is not a target
package, it's a host package, so we cannot add a Python 3 related
dependency to it. So the two solutions that I see are:

 * Change our host-python and host-python3 packages so that they are
   not exclusive from each other, and then find a way for host-scons to
   express the fact that it really needs host-python, and not the
   host-python version matching the selected target python version.
   Note that achieving this might be difficult.

 * Make the three target packages that actually need host-scons
   "depends on !BR2_PACKAGE_PYTHON3". This is a bit ugly, but the next
   version of SCons is supposed to support Python 3, so we could
   consider it as a temporary solution.

Suggestions?

Probably needs some kernel headers dependency. To be checked in detail.
Any taker?

Needs a small patch to support NIOS 2. The only information needed is
to know whether the stack grows upward or downward on the architecture.

Compiler does not provide the right compiler intrinsics. We should
check if more recent versions of gcc do not provide the necessary
intrinsics.
