+commit 75e84ab906ef8935cff3df3d8929f1bafea81599

+
+    perf tools: Fix build breakage if prefix= is specified
+    
+    Invoking Makefile.perf with prefix= breaks the build since Makefile.perf
+    hands that variable down to Makefile.build where it overrides
+    
+        prefix       := $(subst ./,,$(OUTPUT)$(dir)/)
+    
+    leading to errors like this:
+    
+        No rule to make target '/usrabspath.o', needed by '/usrlibperf-in.o'
