my attempt at building gdb on m1 mac to get gdb binary with --target=aarch64-apple-darwin

buildgdb.sh

#!/bin/sh


# install additional dependencies
#brew install gmp mpfr libmpc texinfo pkg-config

# clean old config
# make distclean


# or force a clean
# rm -f config.cache
# find . -name config.cache -print -exec rm -f {} \;
# make distclean || true

# use a sane make - aarch64
# alias make=/opt/homebrew/bin/gmake
# unalias make


# set environment variables for the build
