Solved? I don’t think so. This obligates users either to implement system calls
that are not implemented in SE mode or to transform them into warnings.
Besides, the cross compiler I suggested works perfectly, since it is conceived
to compile applications to run in bare-metal systems. It costs nothing but the
installation of a toolkit. Simpler, don’t you think?

Well, judging by the fact that CentOS’ doesn’t, I doubt it...
