Subject: perf tools: Fix build breakage if prefix= is specified
From: Lukas Wunner <lukas@wunner.de>
commit 75e84ab906ef8935cff3df3d8929f1bafea81599 upstream.
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'
