libroot: Correct no-builtin to be properly focused

* memset.c not arch_memset.cpp like on x86_64
* Sorry for spam

libroot: Compile all arch arch_string with no-builtin

* This was originally added in hrev55661 for x86_64
* riscv64 suffers the same issue after updating to gcc 11
* Presumably, all architectures might suffer from this,
so apply to all remaining architectures

libroot_x86: use the generic memset/memcpy when x86_64 is the primary arch.

the standard x86 implementation uses the commpage, which is difficult to setup. we could
also use the C++11 version instead.

More work towards hybrid support

* All packaging architecture dependent variables do now have a
respective suffix and are set up for each configured packaging
architecture, save for the kernel and boot loader variables, which
are still only set up for the primary architecture.
For convenience TARGET_PACKAGING_ARCH, TARGET_ARCH, TARGET_LIBSUPC++,
and TARGET_LIBSTDC++ are set to the respective values for the primary
packaging architecture by default.
* Introduce a set of MultiArch* rules to help with building targets for
multiple packaging architectures. Generally the respective targets are
(additionally) gristed with the packaging architecture. For libraries
the additional grist is usually omitted for the primary architecture
(e.g. libroot.so and <x86>libroot.so for x86_gcc2/x86 hybrid), so that
Jamfiles for targets built only for the primary architecture don't
need to be changed.
* Add multi-arch build support for all targets needed for the stage 1
cross devel package as well as for libbe (untested).

* Moved the arch specific stuff in src/system/kernel/lib into arch/...
subdirectories. Also moved the x86 kernel arch_string.S there.
* Moved memcpy.c from src/system/libroot/posix/string into the
arch/generic subdirectory.
* Dealt with the consequences of moving things around. Affected are also
the boot loader and runtime loader builds.

Adjust the m68k and ppc parts, too, but only the x86 build is tested.
