CPUs support a large number of performance monitoring events (PMU events)
and often these events are very specific to an architecture/model of the
CPU. To use most of these PMU events with perf, we currently have to identify
them by their raw codes:

	perf stat -e r100f2 sleep 1

So, trying to build this with my set of containers I get lots of failures,
double checking running on another machine with those containers for the
segfault cases, changing sys/fcntl.h to fcntl.h cures the build on alpine:3.4
(musl libc), will try to fix all of them.

The list is incomplete, lots of other systems failed as well.

 1 alpine:3.4: Ok

Fixed with fcntl.h + capping the maxfds parameter to nftw to avoid it
exploding on alloca() in environments where rlim_max is set to a high
value, like in docker.

Now looking at:

Which looks like clashing with stdbool.h...
