Thanks a lot.  You seem to have guided me exactly to what causes the
issue.

This variable seems to be the cause of problems:

$ bitbake -e foo | grep libexecdir=
export libexecdir="/usr/lib/foo"

As far as I understand, package.bbclass may use a user-configured
permissions table (via FILESYSTEM_PERMS_TABLES), but I'm not sure if
this is the right "fix" for the case in question.  I'd have to hardcode
the owner of /usr/lib/foo to be "foo", but foo may not be available when
packaging other recipes.

Should libexecdir actually be in the `target_path_vars' variable
(package.bbclass)?

Best wishes.
Mario
