Cannot build with Ubuntu 21.04 about pongoos

First, I highly recommend you check out #85. Second, if you're on Ubuntu, try adding the Checkra1n repo (and some packages) by doing so:
echo 'deb https://assets.checkra.in/debian /' | sudo tee /etc/apt/sources.list.d/checkra1n.list
sudo apt-key adv --fetch-keys https://assets.checkra.in/debian/archive.key
sudo apt-get update
sudo apt-get install -y ld64 cctools-strip clang llvm gcc.

You can then run:
sudo make -C newlib distclean; sudo make -C newlib all and it should clean your build directory and build the first part anew.

Then, run: sudo make all

This is what worked for me on my WSL2 Ubuntu distro.

Here's a screenshot of what you should wind up with:

EDIT: Sorry to necro an old issue. I just wanted to put this out there to help prevet future repeats of this problem.

Also, having this exact issue in ubuntu 20.04. Ran sudo make -C newlib distclean; sudo make -C newlib all then sudo make all with same results as originally posted. I can start a new ticket if preferred.
