Nearly all targets with OS have memory protection, but bare-metal
targets don't.

If the default is YES, in ${arch}-tdep.c, we should set it to NO, and 
set it back to YES in ${arch}-${os}-tdep.c.  More changes are involved.

Since the number of supported architectures is greater than the number 
of supported operating systems, we'll do less changes if the default is 
NO.  Only have to set it to YES for supported operating systems.
