[PATCH] base.bbclass: If unpacking again, wipe out ${S}/patches

[Richard Purdie]

If we unpack again, its assumed the data in any patches directory is invalid
since do_patch will run again. This ensures old patch data doesn't get
reused in a confused way.

Ideally we should probably wipe out ${S} here but that is probably a change
for another time.

This gets clean *before* do_unpack, right? I have a number of recipes that use sources with patches/ as a toplevel subdirectory.

Yes, bitbake wipes out cleandirs before the task runs. As I mention, we
could in theory wipe ${S} there, I'm just a little more nervous about
that change.
