Subject: [RFC 0/8] tools/build fixes related to eBPF support

Hi Jiri,

	While working on the eBPF patch kit I noticed some problems in the
tools/build/ infrastructure, please take a look and check if they are all sane.

	The last one is not planned for my next perf/core pull req to Ingo,
still requires some more work, but is necessary so that we can exercise the tools/build/
features fixed/introduced in this patchkit.

	There is also that err.h fix from you and a fix for perf probe, because this
is based on my local perf/core branch and will go together in the next perf/core pull req.

	Ah, this is in my perf/ebpf branch at:

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git

https://git.kernel.org/cgit/linux/kernel/git/acme/linux.git/log/?h=perf/ebpf

Thanks in advance,

- Arnaldo
