[Buildroot] [PATCH 0/6] linux: build host perf (branch yem/linux-host-perf)

[Yann E. MORIN <yann.morin.1998@free.fr>]

Hello All!

This short series make it possible to build a host perf.

When run on the target, perf may generate raw dumps. Those dumps are to
be parsed by perf itself to gfenerate proper reports; this can (and
should probably) be done off-line ona fast machine, rather than on the
target.

First, we apply a number of fixes to the perf linux tool:
  - really do not build the documentation
  - honour the number of parallel jobs
  - really disable unavailable features
  - conditioanlly add support for gz and xz

Then, we build perf for the target in an empty directory, rather than
in-place, so that we do not mix the target .o files with the host .o
files.

Finally, we do build the host perf, alsao in its own directory.

Regards,
Yann E. MORIN.
