commit 8f2787e5eb72406231b83a4bc6ee20daa640ab41

    Fix wrong memory access on 32-bit glibc.
    
    off_t on 32-bit glibc is a 32-bit value by default, and building with
    large file is optional.
    
    We also fix the makefile to actually enable large file support.
    
    This isn't an issue on musl since it builds with large file support by
    default.
