diff: delete calls to `chmod -w'

[Fergus Henderson]

configure.in:
scripts/Mmake.rules:
	Delete all calls to `chmod -w'.  Turning off write permission seems
	to cause more problems than it solves.  Amoung other things,
	it causes problems on systems such as Windows where you can't
	delete a read-only file.  (GNU-win32 has some work-arounds for
	that, but there are bugs in the work-arounds.)
	We should probably also delete the various calls to `chmod +w',
	since they are no longer needed, but for the moment I have left
	them in for backwards compatibility.  We can reconsider this
	in a year or two's time.
