    install: Bump compare size limit (128MB) to support large binaries
    
    Preserve metadata and prevent redundant disk writes during builds with
    the install's -C (compare) flag.
    
    The previous historical comparison limit of 16MB is insufficient for
    modern toolchains, frequently choked or bypassed by a large base
    components like LLVM/Clang, kernels, Rust apps, and large runtime
    libraries.
    
    By leaving matching files alone, install keeps their modification timestamps
    intact. make(1) safely ignores those files on subsequent runs.
    
    Base examples: 15.0 amd64 GENERIC kernel - 28MB, clang - 105MB, lldb - 97MB, etc.
