Correctly align the stack. The early csu assumed we passed the aux vector
in through the stack pointer, however this may have been misaligned
causing some userland applications to crash. A workaround was committed in
r284707 where userland would check if the aux vector was passed using the
old or new ABI and adjust the stack if needed. As 4 months have passed it
is time to move to the new ABI, with the expectation the compat code in csu
and the runtime linker to be removed in the future.
