    linux: Fix fstat64 on alpha and sparc64
    The 551101e8240b7514fc646d1722f8b79c90362b8f change is incorrect for
    alpha and sparc, since __NR_stat is defined by both kABI.  Use
    __NR_newfstat to check whether to fallback to __NR_fstat64 (similar
    to what fstatat64 does).
    Checked on sparc64-linux-gnu.
