armv7: s5p4418: make _end compiler-generated

This patch fixes compilation error when we use yocto gcc 6.2.
The dynsym area can be overrapped from bss area. This patch
generates bss end mark by compiler.
Actually, it has been already fixed in arch/arm/cpu/u-boot.lds.

d0b5d9: arm: make _end compiler-generated

This prevents references to _end from generating absolute
relocation records.

This change is binary invariant for ARM targets.
