Which is wrong in case we need specific file from our layer, for different machine or when 2 different recipes have both patch with same name!

Here is example how it fails:

foo_1.0.bb with SRC_URI = "file://bar.patch"
with files:
foo-1.0/om-gta02/bar.patch
foo-1.0/nokia900/bar.patch

Then I don't want to use bar.patch from downloads/bar.patch where it's
from om-gta02 build when I'm building nokia900.

And real example:
I have noticed that even local patches are stored in downloads dir,                    
but today I've noticed that wrong file was used later in do_patch.                                                                                            
I have latest oe-core/meta-oe + latest bitbake.                                                   
                                                                                    
Pulseaudio was building here for first time                                                 
                                                                        
downloads/buildfix.patch is from previous build of xf86-video-intel-2.16.0                    
$ head downloads/buildfix.patch                                                             
Newer mesa doesn't provide dri support, just dri2. The intel driver

pulseaudio has right one:

-c cleansstate doesn't help

rm -rf downloads/buildfix.patch* and probably also -c cleanall _does_ help and do_patch finished now OK.
