From 0afc5cad387db56054b09bb14baf0e6e49df2fd2 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Sun, 1 Mar 2015 21:04:01 +0100 Subject: [PATCH] perf build: Separate feature make support into config/Makefile.feature Move feature related code into separate makefile. The new Makefile.feature is included from config/Makefile. It will be moved later into tools/build.
