I think the approach is still valid, otherwise it would be like if the
target program should know the host. Which reminds me that with
remote_fileio_fstat(), I have the case where my host st_dev has 64 bits,
which doesn't fit into fileio's 32-bit fst_dev.

I think I should resubmit this patch along with my other patch allowing
to "open non regular files" so that I add common device ids (link, fifo,
etc.) to the list of returned fst_dev, and I modify
remote_fileio_fstat() so that it applies the same values to fst_dev.
