In theory， btrfs-tools and other recipes like this will met similar 
problem.


But I tested on btrfs-tools, it don't met problem even without clean, 
since some dependency changed, so

binary btrfs also recompiled. so this is also related to respective 
makefile.


And your suggestion to make it commons also make sense,  in this way,  
we need to

handle condition (${B} and ${S} is same,and CLEANBROKEN = "1")

in base.bbclass and autotools-brokensep.bbclass.   But one problem here 
is  that

we have kinds of recipes,  not all Intermediate file are *.o, how to 
handle this, any suggestion?

or still handle this in seperate recipes?
