commit b2e5e93ae8af6a34bca536cdc4b453ab1e707b8b upstream.
The 'clean' rule in the samples/bpf Makefile tries to remove backup files (ending in ~). However, if no such files exist, it will instead try to remove the user's home directory. While the attempt is mostly harmless, it does lead to a somewhat scary warning like this:
rm: cannot remove '~': Is a directory
Fix this by using find instead of shell expansion to locate any actual backup files that need to be removed.
