    check for _LARGEFILE64_SOURCE instead of __USE_LARGEFILE64
    glibc doesn't define getdents() and requires use of the raw syscall. As
    such lib9/dirread.c needed to decide whether to use SYS_getdents or
    SYS_getdents64 and was checking if __USE_LARGEFILE64 was defined in
    order to do so. musl does not define __USE_LARGEFILE64 so the wrong
    syscall was being used. musl does however define _LARGEFILE64_SOURCE,
    the macro that glibc checks in order to define __USE_LARGEFILE64.
