macos9: remove partial support

The support for compiling on Mac OS 9 hasn't been modified since 2001
and has no active maintainer or packager, so it's time to remove it as
it's incredibly unlikely to work. If a maintainer re-emerges it can be
resurrected from Git history.

Closes: #8836

-MACOS (not MACOS X)
===================
This is the first attempt at porting curl to MacOS.
http, ftp, dict and telnet seems to work fine, other protocols and advanced 
features have not been all tested.

This port is heavily based on the GUSI library from Matthias Neeracher.
GUSI (Grand Unified Socket Interface) is a POSIX/Pthreads/Sockets library 
bringing some of the comforts of UNIX 98 to traditional MacOS.
The latest GUSI release can be downloaded from sourceforge 
at <https://sourceforge.net/projects/gusi/>

I have also written a few functions to help port Unix applications to MacOS.
These functions are part of the GUSI Extra library that can be downloaded at
<http://perso.wanadoo.fr/ela/resources.html#gusiextra>

OpenSSL support is still experimental but I hope to deliver a version 
including SSL soon.

curl for MacOS requires using the CodeWarrior compiler from Metrowerks.

First download GUSI, GUSI Extra and curl. Access paths have been setup so that
GUSI, GUSI Extra and curl directories should have the same parent directory.

Follow the instructions in GUSI Extra "readme.txt" mainly the ones related to
SIOUX and GUSI patches. If you do not apply these patches curl will not behave 
correctly.

In the 'curl/src/macos' directory, decode "curl.mcp.xml.sit.hqx" (This is a 
stuffit binhexed file)
From the CodeWarrior IDE, import 'curl/src/macos/curl.xml', adjust the access 
paths if required. Then you should be able to build:
- the libcurl libraries for PPC and 68K.
- the curl application (also available for PPC and 68K) which is the command
  line version of curl.

If the file "tool_hugehelp.c" is missing rename "curl/src/tool_hugehelp.c.cvs"
to "tool_hugehelp.c" and make sure its file type is 'TEXT'
