[CRIU] [PATCH 00/23] clang support

[Kir Kolyshkin]

Last week I tried to compile CRIU with clang (only for x86_64 for now
to limit the scope; it's already not too small).

The motivation was mostly pure interest to see how CRIU is gcc-dependent.
Also, clang sometimes catches more bugs in the code than gcc which we
can benefit from.

This series is what I ended up with. Tests are OK on my machine as well
as on travis-ci (https://travis-ci.org/kolyshkin/criu/builds/166927121).

Kir Kolyshkin (23):

  Makefiles: move -Wa,--noexecstack out of CFLAGS
  zdtm: compile fix for clang
  zombie00 test: fix for clang
  fpu00 test: fix for clang
  inotify_system tests: fix for clang
  vdso01 test: fix for clang
  groups.c test: fix for clang
  rtc.c test: fix for clang
  apparmor test: fix for clang
  cmdlinenv00 test: fix for clang

  Makefile: don't compile with -O0 if GCOV=1
  CI: move GCOV flag to travis.yml
  zdtm/grow_map: fix test failure for clang
  CI: add clang build for travis-ci
