runtime_loader: add hybrid support.

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).

* Fixed wrong parameter of lazy_mutex_destroy().
* Split locks.cpp into mutex.cpp, recursive_lock.cpp, and rw_lock.cpp (new
subdirectory locks/).
* runtime_loader no longer includes the rw_lock, allowing removal of the TLS
dependency again.

added tls.o to runtimeloader. It linked successfully on x86 because of inlining.

* Also define the build system variables TARGET_STATIC_{LIBSTDC++,LIBSUPC++}.
* runtime loader:
- Fixed gcc 4 warnings.
- Enabled -Werror.
- Renamed all remaining *.c source files to *.cpp.
- Implemented GNU style ELF symbol versioning support.

* Implemented x86 assembly version of memset().
* memset() is now available through the commpage.
* CPU modules can provide a model-optimized memset().

* 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.
