*
* It takes the raw data block set up by the ELF loader
* in the kernel and parses it.
*
* The arguments are:
* elfdata -- The ELF loader data block; usually from the stack.
* Basically a pointer to argc.
*
* onexit -- Function to call on exit, can be NULL.
*
* slingshot -- Address of the program's main function
*
* structors -- Table of constructor functions arrays that must
* be called before the slingshot.
*
* It is called from the assembly fragment found in
* arch-$ARCH/bionic/crtbegin_dynamic.S
