[PATCH 2/12] i386: align data section to 4K boundary

o Currently there is no specific alignment restriction in linker script
and in some cases it can be placed non 4K aligned addresses. This fails
kexec which checks that segment to be loaded is page aligned.

o I guess, it does not harm data segment to be 4K aligned.
