- reworked Do-compile a bit (better failure report output, only build

   with InnoDB support when requested to do so)


Build-tools/Do-compile:
   - only build with InnoDB, if requested to do so (required to be able
     to build 4.0 "Classic" packages without InnoDB support)
   - Enhanced the failure report message subject a little
