H A D | Makefile.feature | 13e96db6 Mon Sep 21 10:24:47 CDT 2015 Arnaldo Carvalho de Melo <acme@redhat.com> tools build: Allow setting the feature detection user
We will use the tools/build/ autodetection in the eBPF patchkit and it is currently sharing the output directory with perf, that also uses the feature detection logic.
As we keep state in the output directory, so that we can avoid running all the tests again, we need to have different filenames for the files used in this state, allow doing that via the FEATURE_USER variable, to be set alongside the existing FEATURE_{TEST,DISPLAY} variables.
v2: Fix comment describing the FEATURE_DUMP filename to make sure where it is created, precisely at $(OUTPUT)FEATURE-DUMP$(FEATURE_USER). Pointed out by Jiri.
