  initial merge of David Paktor's fine work. I redid all of the Makefiles and fixed some minor issues with the code. git-svn-id: svn://coreboot.org/openbios/fcode-utils@76 f158a5a8-5612-0410-a976-696ce0be7e32

   *          ERRMSG_DESTINATION      During development, I used this to switch
   *               error message destination between STDOUT and STDERR, until I
   *               settled on which is preferable.  Recently, I have proven to
   *               my satisfaction that STDERR is preferable:  error-messages
   *               produced by a sub-shell will be correctly synchronized with
   *               the error-messages we produce.  When I tested using STDOUT
   *               for error-messages, that error-case looked garbled.
   *          FFLUSH_STDOUT           fflush( stdout) if error message destination
   *              is STDERR, No-op if it's STDOUT.  A few of these, judiciously
   *              placed, kept our own regular and error messages nicely in sync.
