I'd really prefer the gdbarch callback to stand alone; longer term I think
we ought to get rid of target_info_proc completely and have it just always
use the gdbarch callback.
However, you're right that the target_fileio_ routines fail. I've now fixed
this by making those fall back to the native target if we're not yet connected
to any actual target (>= process_stratum), just like it is already done for
target_get_osdata ...
