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

<link>dynamic:<cxxflags>-DDYNAMIC

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