I'm not sure if we should change the linker script or add BLOCK

In according to the documentation, BLOCK is a synonym for ALIGN for compatibility with the older linker scripts. Given that its name sounds meaningless/confusing,
I would prefer to see the ALIGN in the scripts. Hence I suggest not to add this to LLD but fix the script. How does it sound?
