Ok for this point.

I have tryied this, but, local tools are as old as the kernel. So, I
need to update a lot of tools and there is many dependencies. E.g., I
need to update automake, but my version of autotools is too old to
build a newer version of automake, so, I need to update autotools too,
which have many others dependencies.

If I do that, I will have to use a very old version of glibc. I think
the old version will come with many other problems (bugs and maybe
leak of some functionalities).

I will try to update the kernel on my host machine...
