Describe the bug
I can't install rdkafka via pecl under the php7.1 on Mac M1. Error is: checking build system type... Invalid configuration `arm64-apple-darwin20.5.0': machine 'arm64-apple' not recognized

PHP versions
7.1

To Reproduce

1. Install arm64 version homebrew
2. Install the homebrew-php provided by you tap shivammathur/homebrew-php and install php@7.1 arm64
3. Install rdkafka by pecl then meet a error

Expected behavior
The rdkafka will be installed by pecl success.

Screenshots/Logs

checking build system type... Invalid configuration `arm64-apple-darwin20.5.0': machine `arm64-apple' not recognized
configure: error: /bin/sh /private/tmp/pear/temp/rdkafka/config.sub arm64-apple-darwin20.5.0 failed
ERROR: `/private/tmp/pear/temp/rdkafka/configure --with-php-config=/opt/homebrew/opt/php@7.1/bin/php-config' failed

Actually, I can't install any libs by pecl.

Additional context
I try to use brew install memcached@7.1 --build-from-source another extension from shivammathur/homebrew-extensions, and it works.

And could you fix this pecl issue ?
Or could you please add rdkafka@7.1 into your extensions and give some more details to help my to build and install php c extension manually?

I will add rdkafka to shivammathur/extensions tap.

@ninjachen The issue is that your autoconf auxiliary file config.sub is old and does not recognize macos arm. Make sure you have the latest autoconf and Xcode cli tools, and then try again.

• Update Xcode CLI tools

sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

• Install rdkafka extension.

brew update 
brew reinstall autoconf
brew install librdkafka
pecl download rdkafka-5.0.0
tar xf  rdkafka-5.0.0.tgz
cd rdkafka-5.0.0
phpize
./configure --with-rdkafka="$(brew --prefix librdkafka)" --with-php-config="$(which php-config)"
make
make install

@ninjachen Added rdkafka in shivammathur/extensions tap.

You can use:
brew install shivammathur/extensions/rdkafka@PHP_VERSION

eg: brew install shivammathur/extensions/rdkafka@8.0
