[erlang-patches] Call chmod without the "-f" flag (again)

[Holger Weiß]

Commit 7ed11a88 removed the non-standard "-f" flag from chmod calls in
Makefiles. Meanwhile, new "chmod -f" calls have been added, so this
commit removes the "-f" flag from those new calls:

    git fetch git://github.com/weiss/otp.git update-chmod-without-f
