Support for aarch64/arm64

[josefwegner]

Hi,

I tried to build the ppc-amigaos-gcc crosscompiler on my Raspberry Pi running Raspberry OS (Debian Bullseye aarch64). But it seems that at least for the binutils config.guess and/or config.sub are too old:

...
touch includes-done
make -C ../binutils-build SRC_DIR=../binutils/repo PREFIX=/tmp/adtools/native-build/root-cross CROSS_BUILD_DIR=/tmp/adtools/native-build/binutils-cross-build-2.23.2
make[1]: Entering directory '/tmp/adtools/binutils-build'
mkdir -p /tmp/adtools/native-build/binutils-cross-build-2.23.2
cd /tmp/adtools/native-build/binutils-cross-build-2.23.2; CFLAGS="-Wno-switch -Wno-unused" /tmp/adtools/binutils/repo/configure \
                                                                --enable-plugins \
                                                                --target=ppc-amigaos \
                                                                --prefix=/tmp/adtools/native-build/root-cross

This is my Dockerfile for building:

RUN git clone https://github.com/sba1/adtools.git /tmp/adtools
WORKDIR /tmp/adtools
RUN git submodule init && git submodule update && bin/gild clone && bin/gild checkout binutils 2.23.2 && bin/gild checkout coreutils 5.2 && bin/gild checkout gcc 8
ADD config.guess /tmp/adtools/binutils/repo/
ADD config.sub /tmp/adtools/binutils/repo/
RUN make -C native-build gcc-cross CROSS_PREFIX=/opt/adtools -j4

Would it make sense to add patches with newer config.guess and config.sub? Or would this break other stuff?

[sba1]

You can submit patches, but of course, they should not break other stuff.

I tested this patch on Debian Bullseye ARM64 and Ubuntu 20.04 LTS (ARM64/WSL2). It worked fine on both systems.
