    x11/virtualgl: fix build with lld 17
    
    Building x11/virtualgl with lld 17 results in the following link errors:
    
      ld: error: version script assignment of 'global' to symbol 'clCreateContext' failed: symbol not defined
    
    Since the same linker version script is used for all "libvglfaker"
    library variants, where only one of the implements the clCreateContext
    symbol, suppress errors with lld >= 17 due to this undefined symbol.
