+Subject: tools: Let O= makes handle a relative path with -C option
+
+From: Masami Hiramatsu <mhiramat@kernel.org>
+
+[ Upstream commit be40920fbf1003c38ccdc02b571e01a75d890c82 ]
+
+When I tried to compile tools/perf from the top directory with the -C
+option, the O= option didn't work correctly if I passed a relative path:
+
+  $ make O=BUILD -C tools/perf/
+  make: Entering directory '/home/mhiramat/ksrc/linux/tools/perf'
+    BUILD:   Doing 'make -j8' parallel build
+  ../scripts/Makefile.include:4: *** O=/home/mhiramat/ksrc/linux/tools/perf/BUILD does not exist.  Stop.
+  make: *** [Makefile:70: all] Error 2
+  make: Leaving directory '/home/mhiramat/ksrc/linux/tools/perf'
+
+The O= directory existence check failed because the check script ran in
+the build target directory instead of the directory where I ran the make
+command.
+
+To fix that, once change directory to $(PWD) and check O= directory,
+since the PWD is set to where the make command runs.
