[Qemu-devel] [PATCH v2 00/13] Various build-sys and ASAN related fixes

[Marc-André Lureau]

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
