commit: https://git.buildroot.net/buildroot/commit/?id=f06f58f8fd443968942e100e3c70a29248b2f368
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next
As suggested by Samuel Martin, this commit adds the option
--no-run-if-empty xargs option to the "find ... | xargs ..." logic used
in the python and python3 target-finalize hooks to remove py/pyc/pyo
files. This ensures that the command doesn't fail if there are no files
matching the pattern.
