Hey Zoltan,

I tried to do exactly the same at time I noticed the issue. If I apply 
your patch, the following (and even more related) new warnings are shown 
on my system:

tools/Makefile:153: warning: overriding recipe for target 
'tools/squashfs/clean'
tools/Makefile:153: warning: ignoring old recipe for target 
'tools/squashfs/clean'
tools/Makefile:153: warning: overriding recipe for target 
'tools/squashfs/download'

tools/Makefile:153: warning: ignoring old recipe for target 
'tools/squashfs/prepare'
tools/Makefile:153: warning: overriding recipe for target 
'tools/squashfs/compile'

I've no idea what is going wrong. Instead I've the following change in 
my local tree since a few days (but didn't managed to send it yet):

diff --git a/tools/Makefile b/tools/Makefile

Using this approach the squashfs3 binary is build for ar71xx and ath79 
without these warning.
