cpio: Cannot open: File name too long

Hey there! I'm currently trying to build the containers from the 3.x branch, but I'm running into an issue. When trying to build the OSX container, osxcross complains about there not being an SDK inside the `tarballs/` directory:

```
no SDK found in tarballs/. please see README.md
Error: error building at STEP "RUN if [ -z "${mono_version}" ]; then echo -e "\n\nargument mono-version is mandatory!\n\n"; exit 1; fi && dnf -y install --setopt=install_weak_deps=False automake autoconf bzip2-devel cmake libicu-devel libtool libxml2-devel openssl-devel yasm && git clone --progress https://github.com/tpoechtrager/osxcross.git && cd /root/osxcross && git checkout 17bb5e2d0a46533c1dd525cf4e9a80d88bd9f00e && ln -s /root/files/MacOSX12.3.sdk.tar.xz /root/osxcross/tarballs && patch -p1 < /root/files/patches/osxcross-pr367-fix-github-dl-page.diff && export UNATTENDED=1 && CLANG_VERSION=13.0.1 ENABLE_CLANG_INSTALL=1 INSTALLPREFIX=/usr ./build_clang.sh && ./build.sh && ./build_compiler_rt.sh && rm -rf /root/osxcross/build": error while running runtime: exit status 1
```

After looking through the scripts, it looks like there should be a file at `files/MacOSX12.3.sdk.tar.xz`, but it doesn't exist on my system. I then checked to see where it is created, which is in `Dockerfile.xcode`. After seeing that it is run directly from `build.sh`, I then checked `xcode_packer.log`, where I believe the source of the error is:

```
cpio: ./Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/Vision.framework/MRC5heads_76f6w2kjaz_61501_ay5mhf87cq_97501_hbnrcg6e5e_89040_8g7zthf4q3_12751_rucb99jtq8_75751_8d9qwisndd_85501_concat_quant.espresso.weights: Cannot open: File name too long
cpio: ./Xcode.app/Contents/Developer/Platforms/AppleTVOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/tvOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/Vision.framework/MRC5heads_76f6w2kjaz_61501_ay5mhf87cq_97501_hbnrcg6e5e_89040_8g7zthf4q3_12751_rucb99jtq8_75751_8d9qwisndd_85501_concat_quant.espresso.weights: Cannot open: File name too long
```

From my understanding, this `cpio` error is stopping the Docker script from running, which is preventing the SDK file from being created, which ultimately causes the OSX container to fail.

I'm not sure how to solve this, as I have not changed any of the docker files from the repository, but I had used these same files in December of last year, and March of this year, to build the containers. They worked in both of those instances, and the only thing that has changed is that I am now running Linux Mint instead of Fedora (although from my understanding, since these containers are using a specific Fedora base, I'm pretty sure the host system shouldn't matter?), unless the base image used for these containers has changed since? Any ideas as to how to solve this issue?
