Hi, This turns off D front-end where there's been reported bootstrap problems that need further investigation. Also added a configure.tgt for libphobos to allow enabling for targets where there's known good runtime support backed by existing continuous integration.
For both, this can be overridden if either D or libphobos was explicitly requested by configure. The guards will be loosened as I go through each target configuration. -- Iain --- ChangeLog: 2018-10-30 Iain Buclaw <ibuc...@gdcproject.org> PR bootstrap/87788 PR d/87799 * configure: Rebuild. * configure.ac: Disable D on systems where it is known not to work. libphobos/ChangeLog: 2018-10-30 Iain Buclaw <ibuc...@gdcproject.org> PR bootstrap/87789 PR d/87818 PR d/87819 * configure.tgt: New file. ---
