While working on a concurrency bug, I gave a try to tsan builds for QEMU. I
noticed it didn't build out of the box with recent gcc, so I fixed compilation.
In more, updated documentation to explain how to build a sanitized glib to avoid
false positives related to glib synchronisation primitives.

v3
- rebased on top of master
- previous conversation shifted on why clang does not implement some warnings
- hopefully we can review the content of patches this time

v2
- forgot to signoff commits

Pierrick Bouvier (3):
  meson: hide tsan related warnings
  target/i386: fix build warning (gcc-12 -fsanitize=thread)
  docs/devel: update tsan build documentation
