Remove support for AmigaOS

There is a lot of specialized code for supporting AmigaOS and it has
not been maintained for a number of years.  It's highly unlikely that
the latest versions even compile properly on AmigaOS anymore.  After
requesting that someone step forward to own the maintenance of the
port in the GNU Make 4.4 release and getting no takers, I removed it.

-Short: Port of GNU Make with SAS/C (no ixemul.library required)
-Author: GNU, Amiga port by Aaron "Optimizer" Digulla
-Uploader: Aaron "Optimizer" Digulla (digulla@fh-konstanz.de)
-Type: dev/c
-
-This is a pure Amiga port of GNU Make. It needs no extra libraries or
-anything. It has the following features (in addition to any features of
-GNU Make):
-
-- Runs Amiga-Commands with SystemTags() (Execute)
-- Can run multi-line statements
-- Allows to use Device-Names in targets:
-
-        c:make : make.o
-
-    is ok. To distinguish between device-names and target : or ::, MAKE
-    looks for spaces. If there are any around :, it's taken as a target
-    delimiter, if there are none, it's taken as the name of a device. Note
-    that "make:make.o" tries to create "make.o" on the device "make:".
-- Replaces @@ by a newline in any command line:
-
-        if exists make @@\
-            delete make.bak quiet @@\
-            rename make make.bak @@\
-        endif @@\
-        $(CC) Link Make.o To make
-
-    works. Note that the @@ must stand alone (i.e., "make@@\" is illegal).
-    Also be careful that there is a space after the "\" (i.e., at the
-    beginning of the next line).
-- Can be made resident to save space and time
-- Amiga specific wildcards can be used in $(wildcard ...)
-
-BUGS:
-- The line
-
-    dummy.h : src/*.c
-
-tries to make dummy.h from "src/*.c" (i.e., no wildcard-expansion takes
-place). You have to use "$(wildcard src/*.c)" instead.
-
-COMPILING FROM SCRATCH
-----------------------
-
-To recompile, you need SAS/C 6.51.
-
-As of GNU Make 4.3, the build environment has been cleaned up and alternate
-make files (including smakefiles) have been removed.  If you have an existing
-version of GNU Make available you _should_ be able to run:
-
-   make -f Basic.mk
-
-However this is untested.
-
-If you have an Amiga system and would like to collaborate on getting
-bootstrapping to work properly please contact bug-make@gnu.org.
-
-INSTALLATION
-
-Copy make somewhere in your search path (e.g., sc:c or sc:bin).
-If you plan to use recursive makes, install make resident:
-
-    Resident make Add
