Hi,

This is a small series that improves a bit the build system, and
introduce ASAN by default when --enable-debug. Them it fixes a few
leaks that occur during make check: common and x86_64 target tests are
leak free after this series, the other targets will need some
work. Finally, the last patch should help ASAN and remove some
false-positive, unfortunately it crashes ASAN and may be
incorrect. Help welcome!

v2:
- simplify "build-sys: silence make by default or V=0": make it a
  oneliner MAKEFLAGS, use --quiet.
- document print-VAR rule in docs/devel/build-system.txt
- fix ASAN coroutine instrumentation failure
- should fix builds on gcc 4.4.7 (centos 6)
- new coroutine test leak fix
- add some r-b tags

Marc-André Lureau (13):
  build-sys: fix qemu-ga -pthread linking
  build-sys: silence make by default or V=0
  build-sys: add a rule to print a variable
  build-sys: add AddressSanitizer when --enable-debug if possible
  tests: fix check-qobject leak:
  vl: fix direct firmware directories leak
  readline: add a free function
  tests: fix migration-test leak
  crypto: fix stack-buffer-overflow error
  qemu-config: fix leak in query-command-line-options
  tests: fix qmp-test leak
  ucontext: annotate coroutine stack for ASAN
  tests: fix coroutine leak in /basic/entered

I forgot to update the cover letter: this is no longer true!
