    configure: Disable linker warnings for common symbols
    
    Common symbols are not part of ISO-C and therefore not used
    by FFmpeg at all. Yet linker warnings to ensure it stays
    that way are nevertheless wrong, because the existence of
    common symbols does not imply that there is a bug in our code.
    
    More precisely, Clang's ASAN implementation uses a common symbol
    ___asan_globals_registered when used on Elf targets with
    the -fsanitize-address-globals-dead-stripping option;
    said option is the default since Clang 17 [1].
    This leads to 1883 warnings about ___asan_globals_registered
    when linking here.
    (Even without that option there were warnings like
    _ZN14__interception10real_vforkE being overridden.)
    
    Said warning is also unnecessary: The proper way to ensure
    that our code is free of common symbols is to let the compiler
    enforce this. But this is already the default since GCC 10
    and Clang 11, so there is no risk of introducing our own
    common symbols.
