The patch I've just comitted allows to specify any value of <toolset>,
including subfeatures, inside condition. On the other hand, other feautures
in condition are now validated. For example


now generates an error, since correct spelling is <link>shared. A similiar
error has occured recently in one of the Boost libraries.
