Commit 174a1dcc96429efc ("kbuild: sink stdout from cmd for silent build")
confuses users by sending prompt messages from
scripts/kconfig/conf -s --syncconfig
to /dev/null before start waiting for response to prompt messages
when building with "make -s". Reverting that commit fixes this problem.

Thanks for catching this.
Instead of reverting it,
I'd like to fix the syncconfig part.
