Subject: [PATCH] perf tools: Correct Makefile.include

It looks at O= and adjusts the $(OUTPUT) variable based on what the
output directory will be. However, when O is defined but empty, it
wrongly becomes the user's $HOME dir which is not what we want. So check
it is not empty before working with it further.
