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' Signed-off-by: Lukas Wunner <lukas@wunner.de> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: David Ahern <dsahern@gmail.com> Fixes: c819e2cf2eb6f65d3208d195d7a0edef6108d5 Link: http://lkml.kernel.org/r/5582c48a.84a22b0a.a918.5285SMTPIN_ADDED_MISSING@mx.google.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
