    iucode-tool: fix compile error with musl libc and USE_CPUID_DEVICE
    
    Add patch to fix compilation error with USE_CPUID_DEVICE enabled and musl
    used as libc. Musl doesn't add limits.h header by default and this is
    required if USE_CPUID_DEVICE is used.
    
    The package currently compile because fortify headers include limits.h
    by default.
