Tie this in to the Makefile directly, where we already know what we are

Just forcefully rename the _32 variant overtop, and kill off the now

This adds all of the requisite bits from vmlinux_64.lds.S in to the _32
variant, resulting in a unified and generic linker script that can be

sh64 has traditionally had this configurable via a Kconfig option
(CONFIG_SH64_USER_MISALIGNED_FIXUP). In practice it has never really been
terribly useful to turn this off, so just get rid of the option entirely.

We leave the sysctl around so we don't end up breaking existing root
file systems, and to allow folks that really want this off to do so at
their own risk.

Now that everything has converted over to generic timekeeping, we need an
