[erlang-patches] Implement ./otp_build configure --enable-silent-rules

[Anthony Ramine]

Hi,

I got bored of the too verbose output of the build process, so I added automake's silent rules to Erlang/OTP.

Here is an example of output produced with silent rules: https://gist.github.com/4160201

I may have missed some build tools' invocations as I can only compile Erlang on my Mac.

	https://github.com/nox/otp/compare/erlang:master...enable-silent-rules.patch

	git fetch https://github.com/nox/otp enable-silent-rules

Regards,
