From 1c2d1d8cf4dbef33b8c6af6888bed2f4e659220e Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 3 Oct 2013 15:05:56 +0200 Subject: [PATCH] tools/perf/build: Make sure autodep feature binaries honor the O= setting Arnaldo noticed that the feature-check binaries are generated in the config/check-features/ directory even if O= is specified. Implement $(OUTPUT) logic for config/check-features/Makefile.
