[Buildroot] Why chmod ug+rw?

[Arnout Vandecappelle <arnout@mind.be>]

 Hoi all,

 Why does buildroot make the sources group-writable?

 A bit of context: I'm using Thomas Petazzoni's patch to have a custom package 
extract function that rsyncs the source code into the build directory.  I 
noticed that rsync always goes through the whole tree, because it needs to 
update permissions.  This is because of the below:

	$($(PKG)_EXTRACT_CMDS)
# some packages have messed up permissions inside
	$(Q)chmod -R ug+rw $(@D)

 Now I agree that some packages have messed up permissions, but why does the 
group need read and write permission?  Especially since in buildroot 
everything is owned by the user and no su-ing is done.

 Regards,
 Arnout
