How To Reproduce

1. Clean install Ubuntu 20.04 on Raspberry pi 4 (4gb)
2. Install libusb and clone this repo.

sudo apt install libusb-1.0-0 libusb-1.0-0-dev
git clone --recursive https://github.com/STMicroelectronics/OpenOCD.git
cd OpenOCD

3. Try to build

./bootstrap
./configure
make

Also tried with:

./configure --enable-sysfsgpio --enable-bcm2835gpio

Additional Context
Raspberry pi support would be very handy. Please let me know if I am doing anything wrong.
