[PATCH] Makefile

[PATCH] Makefile

[Georg Nikodym]

When making the docs, the top-level Makefile unconditionally chmod's
three scripts.

Under BitKeeper, things are normally left read-only and the above mode
change is flagged as an error in subsequent BK operations.

BK is can and does track file modes, so BK users can:

	bk chmod +x scripts/docgen scripts/gen-all-syms scripts/kernel-doc
	(bk commit)

The following patch will not harm BK users and behave as always for
others.
