HelperRules: Fix typo in the new CC_IS_LEGACY_GCC test.

configure & build: Rework legacy GCC detection to parse versions outside of Jam.

Jam comparison logic is string-based, and so was detecting GCC >= 10
as being < 2. This rectifies that by removing the GCC version parsing
from Jam logic entirely, and setting various BuildConfig variables
instead.

Remove all invocations of SetSubDirSupportedPlatformsBeOSCompatible.

build: Deprecate SetSubDirSupportedPlatformsBeOSCompatible.

By default, all targets support the "haiku" platform, and we no longer
support building for BeOS, Dan0, Zeta, or other BeOS-compatible targets,
so this is no longer needed.

Also remove all references to the non-Haiku compatible platforms, and
change all BEOS_COMPATIBLE checks to HAIKU_COMPATIBLE. Removal of
all SetSubDirSupportedPlatformsBeOSCompatible invocations
will be in the next commit.

build/jam: whitespace cleanup.

Fix host-only build.

build features/bootstrap repo: support secondary arch

* Add rule FSplitPackageName. It splits a package name into port name
and package suffix.
* FSetConditionsHold: Rename to FConditionsHold and replace the set
parameter by a predicate rule parameter, thus adding more flexibility.
* FIsBuildFeatureEnabled: Use the faster check.
* Add rule FQualifiedBuildFeatureName. Given a build feature name, it
prepends the current packaging architecture to yield a qualified
feature name. Is used by the other build feature rules so that the
same build feature can be configured differently for each arch.
* ExtractBuildFeatureArchives: The supplied list is now filtered via
FFilterByBuildFeatures, allowing for build feature conditions in the
list.
* Add rule InitArchitectureBuildFeatures. It is called early for each
configured architecture, setting up some basic build features for it.
"primary" is set for the primary architecture and a "secondary_<arch>"
is set for each secondary architecture.
* BuildFeatures: Add secondary architecture support: Use the correct
paths for libraries and headers (subdir for secondary architecture)
and configure the icu and zlib sources only for the primary
architecture.
* BootstrapPackageRepository: The package lists are now filtered via
FFilterByBuildFeatures, allowing for build feature conditions in the
lists.
* IsPackageAvailable, FetchPackage: Add secondary architecture support.
* HaikuPortsCross/x86_gcc2: Add icu and zlib x86 secondary packages.

The second stage Haiku cross devel package for the secondary
architecture can now be built.

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).

HelperRules: Add FSetConditionsHold

A rule to check simple element containment conditions on sets.

* Remove now unneeded (hopefully) timezone data

character, returning a component list.

Made the compatibility level for target libbe_test depend on the compatibility
of the host platform. The libtracker Jamfile seems to be the only one that
needs another exception.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21827 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added Haiku as host platform supported by the build system ("haiku_host").
Completely untested yet.

* Added support for compiling Haiku with GCC 4. The main difference is that
we use the libstdc++ (including it's headers) that comes with the
compiler.
* Apparently option "-I-" has been deprecated, which is why we now treat the
include stuff a bit differently.
* Removed avcodec from the Haiku image, since the library wouldn't build with
gcc 4, and I'm not in the mood to fix that (declaration of an array of an
incomplete type).

* Reintroduced third LinkAgainst parameter <mapLibs>, defaulting to true.
Library names are now mapped for all targets but "host" (not only for
"haiku") -- added one more level of indirection to achieve that.
(TARGET_LIBRARY_NAME_MAP -> *_LIBRARY_NAME_MAP_*).
* Renamed build/HaikuBuildCompatibility.h to BeOSBuildCompatibility.h
(auto-included when compiling something that uses the Be API for platform
"host" on anon-BeOS platform), and introduced build/HaikuBuildCompatibility.h,
which can be included when compiling something that can be built for both,
Haiku and BeOS compatible platforms.
* Introduced libhaikucompat.a, a library that adds a few functions existing
under Haiku, but not under BeOS.
* New rule AddSubDirSupportedPlatforms.
* Renamed libopenbeos.so to libbe_haiku.so.
* Introduced new target platform "libbe_test", which is basically equivalent
to a BeOS compatible host platform target, with the exception, that instead
of the host platform's libbe.so a special build of Haiku's libbe.so
(libbe_haiku.so (formerly known as libopenbeos.so)) is used. Furthermore
Haiku's public app, interface, storage, and support kit headers are used
when compiling. This replaces the less nice way in which the test app server
and applications for this test environment were built.
When building for platform "libbe_test", the library name "be" is
autotranslated to "libbe_haiku.so". Thus most applications don't need
special fiddling when them building them for the app server test environment;
usually an "AddSubDirSupportedPlatforms libbe_test ;" will suffice.
* Reduced the dependencies of <syscalls.h> and fixed problems caused by this
(e.g. source files not including the needed headers directly).
