The string with \Arg{crosstch} means that option \Opt{--host} is added to \Prog{configure},
if the project is built with cross-toolchain technology, introduced since \texttt{lfs-10.0}.
In that case the configuration of project contains word \Arg{crosstch},
which is checked by \Prog{ause\_enable}.
When the project is built with earlier \Arg{tools} technology, the word \Arg{crosstch} is absent
and option \Opt{--host} is not added.
