[PATCH 0/2] tools: Add a toplevel Makefile

[Borislav Petkov <bp@amd64.org>]

From: Borislav Petkov <borislav.petkov@amd.com>

Hi all,

here's a refreshed version from yesterday incorporating all comments and
suggestions along with a third patch that adds a 'help' target as the
default one causing the following below. Btw, Arnaldo, could you please
pick those up if there are no complaints since the first patch touches
perf and I don't have a clear idea who else to send it to anyway :).

Thanks.

$ make
Possible targets:

  cpupower   - a tool for all things x86 CPU power
  firewire   - the userspace part of nosy, an IEEE-1394 traffic sniffer
  lguest     - a minimal 32-bit x86 hypervisor
  perf       - Linux performance measurements tool
  slub       - slabs reporting tool
  turbostat  - Intel CPU idle stats and freq reporting tool
  usb        - USB testing tools
  virtio     - vhost test module
  x86_energy_perf_policy - Intel energy policy tool

Cleaning targets:

  all of the above with the "_clean" string appended cleans
    the respective build directory.
  clean: a summary clean target to clean _all_ folders


Changelog:

* v1:

this is a refresh and carve-out of an old patchset. It adds a toplevel
Makefile to tools/ so that one can build the tool of her/his liking by
simply doing

$ cd tools/
$ make <toolname>

By default, we build perf. There's also a scripts/Makefile.lib now which
should contain all make-related generic stuff which can be used by all
tools' build process after including this file.

</Changelog>

Any comments/suggestions are welcome,
thanks.
