ELF loader

A small elf loader. It can load static and dynamically linked ELF EXEC and DYN (pie) binaries. The loader is PIE program that doesn't depend on libc and calls kernel services directly (z_syscall.c).

If the loader needs to load a dynamically linked ELF it places an interpreter (usually ld.so) and a requested binary into a memory and then calls the interpreter entry point.

Default build is for amd64:

$ make

Build for i386:

$ make ARCH=i386

Small build (exclude all messages and printf):

$ make SMALL=1
