                    Configuration variables are supposed to be used in the configure script and are also

                    written to the config file).
                    The <code>name</code> attribute is mandatory, the value is defined by the text body of the element.
                    The optional Boolean <code>exec</code> attribute (false by default) controls, whether the entire
                    definition is automatically executed under command substitution.

                    Multiple declarations for the same named dependency may exist, in which case each declaration
                    is checked one after another, until one block is satisfied. The result of the first satisfied
                    dependency declaration is supposed to be applied to the config file.

                    The configure script shall skip this dependency declaration if the detected platform and toolchain
