 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:

  CC       /tmp/build/perf/fs/tracing_path.o
In file included from /git/linux/tools/include/linux/types.h:4:0,
                 from /opt/android-ndk-r12b/platforms/android-24/arch-arm/usr/include/sys/types.h:35,
                 from /opt/android-ndk-r12b/platforms/android-24/arch-arm/usr/include/strings.h:42,
                 from /opt/android-ndk-r12b/platforms/android-24/arch-arm/usr/include/stdlib.h:36,
                 from pmu-events/json.c:31:
pmu-events/json.h:15:22: error: two or more data types in declaration specifiers
 typedef unsigned int bool;


Which looks like clashing with stdbool.h...
