Implement support for excluded and ad hoc prerequisites
The inclusion/exclusion is controlled via the 'include' prerequisite-specific variable. Valid values are: false - exclude true - include adhoc - include but treat as an ad hoc input For example: lib{foo}: cxx{win32-utility}: include = ($cxx.targe.class == 'windows') exe{bar}: libs{plugin}: include = adhoc
