Hi,

With a toolchain based on binutils 2.25 (patched), gcc 5.1 (unpatched), and newlib 1.20
(unpatched), I get for both h8300h-sim_defconfig and h8s-sim_defconfig:

./arch/h8300/kernel/vmlinux.lds:247: undefined symbol `jiffies_64' referenced in expression

I had to modify arch/h8300/Makefile a bit since the linker does not understand
-mh8300helf_linux and -mh8300self_linux; I had to use -mh8300helf and -mh8300self
instead. Maybe I am missing a binutils patch. I also had to use h8300-linux-elf
as target to convince gcc to accept it as valid target. Both should not result
in the undefined symbol error, though.
