Subject: [PATCH 02/15] perf build: Add dump of features build
Date: Wed, 11 Mar 2015 09:58:51 +0100

Currently you need to hack the features code to get the
features build output. Changing this by dumping the build
output into file during the build.

For each feature 'test-X' new file 'test-X.make.output'
is created and contains the build out. It's created in
the same directory as the feature itself.
