    build: Use get_supported_arguments helper
    
    meson 0.43.0 comes with a new function in the compiler's object
    called `get_supported_arguments`, which allows checking multiple
    optiones at once.
    
    This patch bumps meson's version number and also takes advantage
    of this new feature.
