Masahiro Yamada 8f2db654f7 kbuild: suppress stdout from merge_config for silent builds
merge_config does not respect the Make's -s (--silent) option.

Let's sink the stdout from merge_config for silent builds.

This commit does not cater to the direct invocation of merge_config.sh
(e.g. arch/mips/Makefile).
