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).

Switch wchar from glibc to our own implementations.

Activate our own wcs*tombs()-functions.

* add our own version of these functions to the build
* drop the glibc implementations of those functions

Add implementation of mbsrtowcs() to our locale backend.

* add MultibyteStringToWchar() to ICU locale backend
* implement mbsrtowcs() and mbsnrtowcs() on top of
MultibyteStringToWchar()
* drop respective glibc files

Introduce __set_errno() throughout libroot.

* add errno_private.h, which defines the __set_errno() macro with
and without tracing
* instead of setting errno manually, all libroot's code now invokes
__set_errno(), which makes it much easier to trace changes to errno
* redirect glibc's use of __set_errno() to our own version

Activate our new multibyte implementation.

* add implementations for the following multibyte-related
functions:
btwoc()
mblen()
mbrlen()
mbrtowc()
mbsinit()
mbtowc()
wcrtomb()
wcswidth()
wctob()
wctomb()
* the implementation of the above function live in a symbol
named __<name>, the above symbol names are defined as a weak
alias to the internal ones - TODO: we need to make sure to
only invoked the internal functions (i.e. prepended with __)
in order to avoid problems with symbol preemption.
* deactivate the limited mb implementation we provided before,
as well as respective stuff from glibc

* replace glibc-base wcwidth() and wcswidth() with the one from
Bruno Haible's libunistring, which seems to work just fine

fix the build. Sorry for the trouble

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28999 a95241bf-73f2-0310-859d-f6bbb57e9c96

revert r28970, since they cause crashes. Still looking into it

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28997 a95241bf-73f2-0310-859d-f6bbb57e9c96

Imported some wide char functions from freebsd, adapted to the build, tried to integrate them with the glibc we are using. The mbtest supplied in ticket #2822 seems to work, without regressions. Please shout if there are issues.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28970 a95241bf-73f2-0310-859d-f6bbb57e9c96

added some tsearch and iconv functions,


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22533 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16728 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added PPC specific and some generic glibc headers. Taken from
glibc 2.3.2, which seems to be the version used in other places,
though I also found older files.

* 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.

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


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12361 a95241bf-73f2-0310-859d-f6bbb57e9c96

Renamed src/kernel to src/system.
