m68k-elf-gcc: fails to build on macOS/arm64 13.2.1 (config.sub: invalid option -apple-darwin22.3.0)

m68k-elf-gcc fails with the error:

make: *** No rule to make target `all'.  Stop.`

The Makefile exists in the work directory, but is empty.

The key errors seem to be:

:info:configure checking host system type... config.sub: invalid option -apple-darwin22.3.0
1190	:info:configure Try `config.sub --help' for more information.
1191	:info:configure checking target system type... m68k-unknown-elf
1192	:info:configure checking build system type... config.sub: invalid option -apple-darwin22.3.0
1193	:info:configure Try `config.sub --help' for more information.

Note: I was able to successfully install i386-elf-gcc on the same system. That port is based on a much later version of gcc:

/opt/local/bin/i386-elf-gcc --version
i386-elf-gcc (GCC) 12.2.0

whereas this port is still using GCC 3.4.6.

See also #67162 for mips-elf-gcc which is similarly out of date.

Even if you fix this error, there are a bunch of other ones including implicit declarations. Updating the port to a newer gcc version is indeed likely to be the easiest path forward.
