    build: fix warning with latest version of meson
    
    The warning was:
    
    WARNING: -Wl,--version-script looks like a linker argument, but has_argument
    and other similar methods only support checking compiler arguments.
    Using them to check linker arguments are never supported, and results
    are likely to be wrong regardless of the compiler you are using.
