Remove: MorphOS / AmigaOS support

In 10 years there is no commit to change how MorphOS works, and we
have no active maintainer for it. It is unlikely it works in its
current state (but not impossible).

With the arrival of SDL2 (and removal of SDL), MorphOS is no longer
support. There is an SDL2 port for MorphOS, but it is not maintained
by upstream SDL2, and nobody can currently test it out.

If anyone wants to re-add MorphOS, please do (revert this patch,
fix the problems, and create a Pull Request). If you need any help
doing so, let us know! It is not that we don't like MorphOS, it is
that we don't have anyone fixing the problems :(

-
-Use '`make`'. However, for the first build one has to do a '`./configure`'
-first. Note that you need the MorphOS SDK, latest libnix updates (else C++
-parts of OpenTTD will not build) and the powersdl.library SDK. Optionally libz,
-libpng and freetype2 developer files.
-
 ### OS/2:
 
 A comprehensive GNU build environment is required to build the OS/2 version.
