Debugged, the patch is broken.

Using a little tool I have:

Task qemu-system-native-5.2.0-r0:do_addto_recipe_sysroot failed
Active tasks are:
virglrenderer-native-0.9.1-r0:do_rm_work
binutils-cross-arm-2.36.1-r0:do_patch
qemu-system-native-5.2.0-r0:do_addto_recipe_sysroot
qemu-system-native-5.2.0-r0:do_rm_work
libepoxy-native-1.5.5-r0:do_rm_work
gcc-source-11.1.0-11.1.0-r0:do_unpack

Note how qemu is simultaneously adding itself to the sysroot, whilst
rm_work is running and deleting the sysroot.

This patch isn't compatible with rm_work and should be reverted.
