[PATCH] conditional patch-tool dep

[Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>]

Hi,

If a recipe doesn't reference any patch then patching doesn't make sense
and neither does depending on patch-tool.

I didn't look yet if i can say
addtask patch after do_unpack if needs_patching_at_all(d)
(or something like that).
So, for a start, don't depend do_patch on the patch tool if there is no
patch in the SRC_URI.

untested.

PS: There should be some oe.is_compressed(uri) shorthand that is used to
decide if an uri is in a compressed format, imho.
