Siddhesh Poyarekar 533bb7c2ae Fix stack alignment when loader is invoked directly 
The s390 ABI requires the stack pointer to be aligned at 8-bytes.
When a program is invoked as an argument to the dynamic linker,
_dl_start_user adjusts the stack to remove the dynamic linker
arguments so that the program sees only its name and arguments.  This
may result in the stack being misaligned since each argument shift is
only a word and not a double-word.

This is now fixed shifting argv and envp down instead of shifting argc
up and reclaiming the stack.  This requires _dl_argv to be adjusted
and hence, is no longer relro.
