building error on MacOS (ARM) 13.6 (M1 Pro MacBook) about obfuscator-llvm

Hi @MarkMjw, I moved your comment here as it's related to ARM cpu of the Mac M1

The endianness check missed ARM build options

I just checked compilation on a Ampere Altra.
I will check obfuscation on openssl later and push a merge request.
