Thanks, merged.

However there were a couple issues:

- the bashism in patch 4, replaced by

+meson_option_build_array() {
+  printf '['
+  (if test "$targetos" == windows; then
+    IFS=\;
+  else
+    IFS=:
+  fi
+  for e in $1; do
+    e=${e/'\'/'\\'}
+    e=${e/\"/'\"'}
+    printf '"""%s""",' "$e"
+  done)
+  printf ']\n'
+}
+

- oss-fuzz didn't work, it has a syntax error and also can be simplified 
to use qemu-bundle as well, like

-# Copy over the datadir
-cp  -r ../pc-bios/ "$DEST_DIR/pc-bios"
+# Prepare a preinstalled tree
+make install DESTDIR=$DEST_DIR/qemu-bundle
