Kusanagi Kouichi ecafda60e8 perf tools: Fix build error on read only source. 
Parts of the build process were generating files outside the specified
O= directory, causing the build to fail on systems where the sources are
in a read only file system.

Fix it by using $(OUTPUT) on these locations.

Also check that $(OUTPUT) actually exists, just like the top level
kernel Makefile does. Otherwise the failure message emitted is
completely misleading.
