* Fix adding WebPositive optional package.
* Fix adding wonderbrush package. Add it only for gcc2 to avoid a
warning by AddHaikuImagePackages.
* Simplify adding xz_utils package.
* find_directory() and hard-coded paths use /boot/system instead of
/boot/common.
* The build system creates the writable directories in /boot/system
instead of /boot/common.
* The build system no longer installs any packages in /boot/common.
The Haiku bootstrap image is now built with (hopefully) all required
primary and secondary architecture packages. The runtime loader is still
resisting our wish to run secondary architecture programs, though.
* Don't handle the bootstrap case in the main Jamfile. Add all bootstrap
packages to the image in the profile definition. That's less
confusing, hopefully.
* Add the missing bootstrap packages (ncurses*, libtool_libltdl). The
would normally be added in build_haiku_image when the package
dependencies are resolved, but we don't do that for the bootstrap
image, since we intentionally leave some dependencies out (e.g. perl)
because they can be built.
DefaultBuildProfiles is now included earlier (right after BuildSetup).
This allows us to set HAIKU_BOOTSTRAP_BUILD earlier, so it can be used
for the repository selection. The actual build profile definitions,
which cannot be done that early, live in the rule
DefineDefaultBuildProfiles, which is invoked where the file was
previously included.
