The following patches are to use @target_noncanonical@ and
@host_noncanonical@ in GDBserver.  In order to make review easier, I
split the patch into two, #1 is to revert two previous commits, and #2
is to use noncanonical stuff.  These two patches should be committed to
cvs in one go.  Here is the patch 1/2.

I tested these patches by build gdb via 'configure & make' and
'configure --host=mips-linux & make', the generated version.c looks
right to me.
