The git module allows basic access to git. Hosts are now required
to provide git support.
The defaults module now returns options as a list split on '='.
Remove the need to add the --force option. Also revert the force option
back to the --force from --no-force and leave it so the user can
bypass the host check of various packages.
Add arch build files. This allows archs to have different versions
and patches for specific tools.
Break the RTEMS config directory up into separate directories to
make long term maintenance easier. This required a change to config.py
to handle the config files being in subdirs of the config directory.
The defaults have been updated to include the install SB root so
packages built before a package are available.
Add makeinfo to the required tools. GDB (and others) need it to
build without error.
Add per arch build sets as this is really what RTEMS needs. You
can then vary the version based on the architecture.
Add '%include' to the buildset files.
