CRIS port 8/8: doc updates

[Ulrich Drepper]

I've applied the patches now with some modifications and exceptions:

- several files in sysdeps/unix/sysv/linux/cris were using x86 files which
  are there only for compatibility with pre-glibc 2.2.  Since 2.2 is
  the first release supporting the configuration this isn't necessary.

- I've stripped the sysdeps/cris/Makefile a lot.  No system-specific
  rules, you can keep them in your tree for development.  But there is
  no need to have them in the official tree.

  The main change is that I removed this -mpdebug stuff.  This won't fly.
  Either fix the assembler or modify the glibc macros to not cause
  problems.


One more comment: which is the first kernel supported?  I guess it's
some 2.4 version.  In this case you can remove a lot more of the files
in sysdeps/unix/sysv/linux/cris which are there only for compatibility
with old kernels.

Regarding the Dist files, they will be OK.  I'll handle them the next
time I'm making a release.

Thanks,
