	I believe that glibc (including the ld.so dynamic linker) extract
the arguments and place them into registers before calling main().

	For instance, glibc sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c
defines a macro called

DL_FIND_ARG_COMPONENTS(cookie, argc, argv, envp, auxp)

which is used by glibc to extract argc/argv/envp from the auxilliary
argument block.
