[TASK] <title> Errors including undefined reference to `__atomic_compare_exchange_4' when running "make images" command

Is there an existing CVA6-SDK task for this?

Task Description

I'm trying to run the "make images" so I can make a bootable SD card. However, it is not working since I get the following error:/mnt/c/Users/PMLS/Downloads/cva6_sdk_master/buildroot/output/host/bin/riscv64-buildroot-linux-uclibc-nm: libc/stdlib/__cxa_finalize.os: file format not recognized

Description of Done

I need to make bootable SD card. For now I'm using the prebuilt bitstream of CVA6 along with its prebuilt Linux image and memory configuration file since those commands ("make fpga" for bitstream on the cva6 repo) also don't work. The prebuild of the Linux image includes the bbl.bin file which I guess is the Linux image(which I'm guessing is equivalent to the vmlinux image and uImage.bin files), however, I also need the fw_payload.bin file and "make fw_payload.bin" also returns an error identical to the one above. Clicking on the buildroot directory in this repo leads to a 404 web page. So I went ahead and downloaded the latest version of Buildroot from its official gitlab repo and unzipped it into the empty buildroot file.
After researching myself for sometime, I have a suspicion it might be due to using the latest version buildroot, however I can't determine what version of buildroot was used in this repo since it leads to 404 web page. Or maybe the problem could be with something else(there was a similar problem people online had with gprc and deprecating the version solved their problem).
