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

[Anthony Ramine]

I could do that, it would make things easier. The patch doesn't yet handle all the things but I
submitted it anyway to have a feedback earlier and to know whether I should bother finishing it.

I guess your answer is positive enough for me to finish it :) I'll do that this weekend.

Regards,

Should I be bothered by obscure GCC flags that don't concern me while doing so? Should I not be able to view the various warnings caused by my changes with just a glance? I could use GCC's -Werror but what should I do about warnings that are independent of my tinkering?
