[svn-r2938] Purpose:
    pathc
Description:
    TFLOPS coredumped on h5ls because when h5ls calls ioctl(TIOCGWINSZ),
    the ioctl() routine coredumped inside.
Solution:
    It is likely that TFLOPS does not support window-size in the
    compute nodes.  Still, it should not coredump.  Bypass it for
    TFLOPS for now.
Platforms tested:
    TFLOPS & modi4 (-64)
