updated NetWare docu.

   - recent Novell LibC SDK available from:

     http://developer.novell.com/ndk/libc.htm

   - optional zlib sources (at the moment only dynamic linking with zlib.imp);

   - or recent Novell CLib SDK available from:

     http://developer.novell.com/ndk/clib.htm

   - optional zlib sources (static or dynamic linking with zlib.imp);

     sources with NetWare Makefile can be obtained from:

     http://www.gknw.net/mirror/zlib/

   - optional OpenSSL sources (version 0.9.8 or later which builds with BSD);

   - optional OpenSSL sources (version 0.9.8 or later build with BSD sockets);

     you can find precompiled packages at:

     http://www.gknw.net/development/ossl/netware/

     for CLIB-based builds OpenSSL needs to be extended to build with BSD

     sockets (currently only a winsock-based CLIB build is supported); 

   - optional SSH2 sources (version 0.15 or later);

   Set a search path to your compiler, linker and tools; on Linux make

   sure that the var OSTYPE contains the string 'linux'; and then type

   sure that the var OSTYPE contains the string 'linux'; set the var

   NDKBASE to point to the base of your Novell NDK; and then type

   'make netware' from the top source directory; other tagets available

   are 'netware-ssl', 'netware-ssl-zlib', 'netware-zlib' and 'netware-ares';

   if you need other combinations you can control the build with the

   environment variables WITH_SSL, WITH_ZLIB, WITH_ARES and ENABLE_IPV6.

   environment variables WITH_SSL, WITH_ZLIB, WITH_ARES, WITH_SSH2, and

   ENABLE_IPV6; you can set LINK_STATIC=1 to link curl.nlm statically.

   I found on some Linux systems (RH9) that OS detection didnt work although

   a 'set | grep OSTYPE' shows the var present and set; I simply overwrote it

   with 'OSTYPE=linux-rh9-gnu' and the detection in the Makefile worked...
