Ensure apps are linked with 4k page size

All our lds assume a 4k alignment. Without this, on archs like aarch64
where the linker may assume a larger page size (64k), gnu ld will end up
merging .text and .data sections into the same segment.

This results in the segment being RWE which will cause a fatal warning
(and is a bad thing anyways)
