If you'd like, I believe arm*-*-eabi and arm*-*-elf should XFAIL the
args.exp and fileio.exp failures.  I believe they're inherent; ARM
defined the semihosting interface (long ago), and it does not include
the necessary bits for some of this.  For instance, the command line
is passed as a string.  It's possible some of the fileio.exp failures
are bugs in the simulator though - I haven't checked them exhaustively.

Same spelling errors as last patch.
