'poky/build/tmp/work/x86_64-nativesdk-pokysdk-linux/gcc-cross-canadian-arm/12.2.0-r0/recipe-sysroot/usr/include/asm/byteorder-32.h'
In this particular case, the paths in lib32-linux-libc-headers manifest file
are prefixed with lib32-recipe-sysroot:
$ cat build/tmp/sysroots-components/manifests/lib32-linux-libc-headers.xxx
lib32-recipe-sysroot/usr/include/asm/byteorder-32.h
lib32-recipe-sysroot/usr/include/asm/sigcontext-32.h
...
When gcc-cross-canadian-arm is built, the actual files get copied to
recipe-sysroot directory during do_prepare_recipe_sysroot().
Because of this mismatch, on rebuild, sstate_clean_manifest() will not clean
the files in recipe-sysroot, but will instead try to delete the non-existent
files in lib32-recipe-sysroot. This will trigger the FileExists errors later.
Add checks in sstate_clean_manifest() for this corner case, so that
RECIPE_SYSROOT gets cleaned up properly.
This fixes BZ#15045.

How many recipe-sysroots are there for gcc-cross-canadian-arm ? This
feels like a workaround for some other issue which should probably be
fixed properly instead?
(resending, as the first reply didn't actually made it to the list)
There are "recipe-sysroot" and "recipe-sysroot-native" sysroots in
gcc-cross-canadian-arm WORKDIR, but no lib32-recipe-sysroot.
