    perf tools: Fix build error on read only source. · ecafda60
    Kusanagi Kouichi 提交于
    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.
