Xash3D fails to link on arm64 macOS 13.2.1

[chinese-soup]

Hello. First all of all I wanted to thank you for the project you're making here!

The build works just fine, apart from the occasional segfaults on startup (and shutdowns), I wanted to experiment around and built it myself from source, the HLSDK builds fine, however I am hitting a linker(?) error on macOS 13.2.1 with filesystem_stdio:

Could you help me with any clues as to what might be wrong? Thanks!

Never mind, it was an ar(1) issue where clang doesn't like GNU binutils. As a workaround I didn't uninstall binutils (since Xash still needs objcopy, but just renamed /opt/homebrew/opt/binutils/bin/ar to /opt/homebrew/opt/binutils/bin/ar.gnu)
