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).

Use the new <asm_defs.h> header in x86 assembly files. Particularly
added FUNCTION_END() calls for a good deal of functions. The respective
ELF symbols do now have a correct size.

siglongjmp() calls __longjmp_return() also on x86, now. This resets the
signal mask as required. and also makes my recent return value fix
unnecessary, since __longjmp_return() already does that.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25430 a95241bf-73f2-0310-859d-f6bbb57e9c96

Reimplemented setjmp(). It no longer offsets the caller's esp.

* Implemented [sig]{set,long}jmp() for PPC. No idea, if it is any good,
but it compiles at least. :-)
* Pulled the architecture specific part out of <posix/setjmp.h> into
<posix/arch/<arch>/arch_setjmp.h>.
* Moved setjmp_save_sigs.c from the x86 specific implementation into a
"generic" sibling directory, since it is reusable (and actually used
by the PPC implementation).
* Added generic/longjmp_return.c containing a function __longjmp_return,
which is invoked at the end of siglongjmp(), resetting the signal mask
and validating the return value. It is used by the PPC implementation,
and should also be used by the x86 implementation, but I'll leave that
to someone who's motivated enough to also test it. :-)

* libroot and the runtime loader are no longer built with kernel rules.
* New rule Ld, analogously to KernelLd.
* Added StaticLibrary parameter for supplying additional objects.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15191 a95241bf-73f2-0310-859d-f6bbb57e9c96

added some x86 glibc functions (more to come)
we might miss some wrappers for some ieee754 functions (to check)
hope nothing is broken

setjmp() is now an assembly stub that doesn't create a stack frame but just
jump to sigsetjmp(). I'm a bit irritated that the previous version didn't
run as expected, but it now does.
This needs some more investigation.

This should fix the build after all the kernel/system renaming.
If anything is still broken (and was not before :)), please shout.
