OptionalPackages. This makes the content definition part in
AlternativeGCCArchive superfluous.
* Moved the cc and c++ wrapper scripts from src/bin to data/bin.
* Added build variable HAIKU_ADD_OPTIONAL_PACKAGES to add optional packages
-- the list can be separated by slashes to allow easier passing through
the shell.
* When invoking the sub-jam that builds the alternative GCC archive, we force
it to ignore the UserBuildConfigs and we enable the optional packages
enabled in the main jam.
* Reorganized /boot/develop:
- There's now an "abi" subdirectory containing a <arch>/<gcc>/ subdirectory
for each installed ABI-incompatible gcc version and a "current" symlink
pointed to the currently selected one.
- All ABI-dependent directories under /boot/develop/ (lib/x86, headers/cpp,
tools/gnupro) symlink into /boot/develop/abi/current.
- Changed BELIBRARIES to contain
/boot/develop/abi/current/library-paths/common instead of /boot/common/lib.
The former is a symlink to either /boot/common/lib or
/boot/common/lib/<gccVersion>. There's also a respective "home" symlink.
- Repackaged the optional binutils+gcc 2/4 packages accordingly. Also fixed
the obsolete /boot/beos/system/lib/libstdc++.so symlink in the gcc 4
package.
- The new structure allows to switch between compilers by changing the
/boot/develop/abi/current symlink. Added script setgcc to do that.
