Group name is now part of the local configuration

Until now, the group name to build the project actually went into the Git
source of the project! This doesn't allow exact reproducibility on
different machines (where the group name may be different).

With this commit, the `for-group' script has been modified to accept the
group name as its first argument and pass that onto `configure' and
Make. This is much better now, because not only the existance of a group
installation is checked, but also the name of the group. It also made
things simpler (in particular in `LOCAL.mk.in').
