kbuild: suppress stdout from merge_config for silent builds
[ Upstream commit 1f937a4bcb0472015818f30f4d3c5546d3f09933 ]
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).
