+Subject: [PATCH 07/12] qemu: Determinism fixes
+
+When sources are included within debug information, a couple of areas of the
+qemu build are not reproducible due to either full buildpaths or timestamps.
+
+Replace the full paths with relative ones. I couldn't figure out how to get
+meson to pass relative paths but we can fix that in the script.
+
+Upstream-Status: Pending [some version of all/part of this may be accepted]
