makefile: quiet output support

Support for quiet output (without all the flags and compile
options): make Q=1 or make QUIET=1.
It can be saved in the config (e.g. make config Q=1) and it can be
overridden any time (e.g. make utils Q=0).
Compilation is a little faster in quiet mode and the same speed as
before in normal mode.

Example module output:
CC (gcc) [M tm.so]              uac.o
LD (gcc) [M tm.so]              tm.so

Lib example:
LD (gcc) [L libbinrpc.so.0.1]           libbinrpc.so.0.1
