Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:

   1. Rtems contains some perl scripts that use hard-coded paths to
      /usr/bin/perl or /usr/local/bin/perl I have already fixed these
      problems by adding some checks to configure.in.   While doing this,
      I also cleaned up some more autoconf related problems for generating
      shell scripts.  This patch might seem a bit scary to you, but I am
      quite confident it won't break something (I've been testing it for
      almost a week now, however it might introduce typos for a limited
      number configurations I don't have access to - But it shouldn't be
      a problem for you to test them :-).

   I expect to get this finished tonight, hence you will very likely
   have the patch when you get up tomorrow.

   Changes:

   * Check for PERL and disable all PERL scripts if perl wasn't found.
   * Generate all KSHELL-scripts with autoconf instead of make-script
   * Automatic dependency handling for autoconf generated KSHELL or PERL
     scripts (make/rtems.cfg)

   Notes:
   * this patch contains new files and deletes some other files.
   * The patch is relative to rtems-4.0.0-beta4 with my previous
     rtems-rc-981014-1.diff patch applied.

   Testing:
      I tested it with sh-rtems and posix under linux. Now all targets
      which are touched by this patch and which are not used while building
      for sh-rtems and posix still need to be tested. AFAIS, only the
      sparc/erc32 BSP should be affected by this criterion. And if you
      like to, you should also consider testing it on a Cygwin32 and a
      Solaris host for one arbitrary BSP.
