Fix iOS clang compiler flags for dylib creation

- Change -sysroot to -isysroot for iOS compatibility
- Fix all dylib creation commands in script
- Resolves 'unknown argument -sysroot' clang error
- Should now successfully create libbox64.dylib from interpreter objects

This fixes the final compilation error preventing framework creation
