This is a mechanical change that is required to get the current sources to 
build at all for arm-netbsd native.  I guess the code I developed the 
NetBSD sources for must have predated this global change.

With this and previous patch at least cvs gdb will now build on arm-netbsd.

[ The testsuite results are somewhat horrible :-( ]
