Change subject: misc: Make the m5 utilities writefile command accept a host  
path.
......................................................................

misc: Make the m5 utilities writefile command accept a host path.

When the writefile command is given one command line argument, it's treated
as the name of the file in the simulation and on the host. When there are  
two
arguments, the first is the filename in the simulation, and the second is  
the
name on the host.
