Sebastian Sumpf 5611020f33 hw: fix stack alignment in bootstrap for x86_64
Fix initial stack pointer alignment for x86_64 in crt0.s startup code of
bootstrap. SysV ABI states that upon function entry (rsp + 8) % 16 = 0.
There, we have to align the stack to 16 bytes before all 'call'
instruction not 8. Otherwise FPU (GP) exception might be raised later on
because of unaligned FPU accesses.
