From: Lukas Wunner <[email protected]>
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'
