Almost certainly something that make is running is asking you a
question, but since you are buffering the output through the pipe and
into tee, most likely in line-buffered mode, the question is not being
printed since it doesn't end in a newline.

So, it's just sitting there waiting for you to answer, for 24
hours... or as long as you want to wait :-).  Once you do, it will print
both the question and your response :-/.


Either don't preserve the log at all, or use something like script
instead of pipe to tee.  script uses a pty as stdout, so you don't run
into these kinds of issues.
