+From: Riku Voipio <riku.voipio@linaro.org>
+
+Perf is shipped in debian in linux-tools-$version package. Extend
+the existing to builddeb script to build perf if BUILD_TOOLS=y
+is added the make deb-pkg line
+
+Some features of this patch I'm uncomfortable with:
+
+1. Relative paths are resoved to absolute ones
+   Especially with separate O= buildd, perf build from tools/perf dir
+   fail.
+
+2. Unsetting LDFLAGS
+   make -> shell (builddeb) -> make expands variables. The LDFLAGS as
+   set by toplevel makefile are for kernel, so we just unset the flag
+   here.
+
+3. Replaces ubuntu/debian packages instead attempting to fit to
+   the linux-base/linux-tools-common frameworks. I think people who
+   want to run "make deb-pkg" for their kernels would rather keep this
+   simple.
+
+4. More tools than just perf could be built - unfortunately most
+   tools fail to have a working "install" target and/or else have
+   build process inconsistent with other tools. A topic for another
+   patch series.
