I'd like to avoid this if we can.  On OpenBSD we include GDB in the
base system, but we don't have GNU make.  This'll mean I'll have to do
extensive makefile hackary whenever I import a new version of GDB in
the OpenBSD tree.  I'd rather spend that time on hacking more useful
stuff.

Given the way CVS handles time stamps on checkouts, this probably gets
me in the same situation as above.
