Can SITE_METHOD = local be used with a custom tarball?  My
understanding from the docs is that it requires an unpacked source
directory tree [in which, as you said, one can easily apply whatever
patches are required].

I agree that for the unpacked source directory tree use case, not
appying patches makes the most sense.
