There isn't any data about this that I know of.
The patch says
provided that files created in that directory are deleted before the
target completes and are not reused by subsequent executions of the
target.
rather than
but files created in that directory must be deleted before the
targets completes and must not be reused by subsequent executions of
the target.
so I don't think applying this patch would make a package RC-buggy
simply because it left some things behind in /tmp.
On the other hand, if a package built differently the second time
because of some things left behind in /tmp, that would surely already be
considered to be a bug, possibly RC, depending on what the differences
were.
