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'
