From be73c78420d9a23accfa9568e451046272ceab84 Mon Sep 17 00:00:00 2001

Subject: [PATCH] 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.
