[Buildroot] [git commit master 1/1] package/config: create .depend in object directory

[Quotient Remainder]

I get a (non-fatal) permission denied error when I do "make distclean"
and I've tracked it down to this change, I think.
It appears that $(obj) has an empty value when this is invoked.  I did
not do an out-of-tree build, btw.

        /mnt/LinM/git/lvgit5/buildroot-reatha$ make menuconfig
        ...
        
        /mnt/LinM/git/lvgit5/buildroot-reatha$ make
        ... (this is successful)
        
        /mnt/LinM/git/lvgit5/buildroot-reatha$ make V=1 distclean
        rm -rf     \
        		 /mnt/LinM/git/lvgit5/buildroot-reatha/output/build 
        rm -rf output
        rm -rf /mnt/LinM/git/lvgit5/buildroot-reatha/.config /mnt/LinM/git/lvgit5/buildroot-reatha/.config.old /mnt/LinM/git/lvgit5/buildroot-reatha/.config.cmd /mnt/LinM/git/lvgit5/buildroot-reatha/.auto.deps

As you can see it attempts to create a file in the system root
directory.
