Subject: [PATCH] Fix crash when running QtCore: Stack is misaligned on x86-64

When our ELF entry point function is started by the kernel, the stack is
aligned at 16 bytes. However, the stack is expected to be off by 8, due
to a preceding CALL instruction which didn't exist. This cauases a crash
further down as the compiler may generate aligned stack access.
