This was originally several commits that had to be squashed into one
because the intermediate states weren't able to build coreboot:
- one to remove everything that wasn't our own code, leaving only
regex.[ch], toada.c, description.md and Makefile.inc.
- one to copy in Linux 5.13's scripts/kconfig and adapt Makefile.inc
to make the original Makefile work again.
- adapt abuild to use olddefconfig, simplifying matters.
- apply patches in util/kconfig/patches.
- Some more adaptations to the libpayload build system.
The patches are now in util/kconfig/patches/, reverse applying them
should lead to a util/kconfig/ tree that contains exactly the Linux
version + our own 5 files.

Using the linker's --wrap feature has the downside that it only covers
references across object files: If foo.c defines a() and b(), with b
calling a, --wrap=a does nothing to that call.
Instead, use objcopy to mark a weak and global so it can be overridden
by another implementation, but only for files originating in src/.
That way mocks - implemented in tests/ - become the source of truth.
TEST=Had such an issue with get_log_level() in a follow-up commit, and
the mock now takes over. Also, all existing unit tests still pass.

Memlayout is a mechanism to define memory areas outside the normal
program segment constructed by the linker. Therefore, it generally
doesn't make sense to relocate memlayout symbols when the program is
relocated. They tend to refer to things that are always in one specific
spot, independent of where the program is loaded.
This hasn't really hurt us in the past because the use case we have for
rmodules (ramstage on x86) just happens to not really need to refer to
any memlayout-defined areas at the moment. But that use case may come up
in the future so it's still worth fixing.
This patch declares all memlayout-defined symbols as ABSOLUTE() in the
linker, which is then reflected in the symbol table of the generated
ELF. We can then use that distinction to have rmodtool skip them when
generating the relocation table for an rmodule. (Also rearrange rmodtool
a little to make the primary string table more easily accessible to the
rest of the code, so we can refer to symbol names in debug output.)
A similar problem can come up with userspace unit tests, but we cannot
modify the userspace relocation toolchain (and for unfortunate
historical reasons, it tries to relocate even absolute symbols). We'll
just disable PIC and make those binaries fully static to avoid that
issue.

The current test framework builds the test code without any warnings at
all, which isn't great -- we have already slipped in some cases of
non-void functions not returning a defined value, for example. It would
likely be overkill to try to use all the same warnings we use for normal
coreboot code (e.g. some stuff like -Wmissing-prototypes makes cmocka's
__wrap_xxx() mock functions unnecessarily cumbersome to work with, and
other things like -Wvla may be appropriate for firmware but is probably
too aggressive for some simple test code). Therefore, let's just add
some of the stuff that points out the most obvious errors.
