[Buildroot] Overriding DL_DIR in the environment

[Ulf Samuelsson]

I keep a central download location for all tarballs,
and find it a pain to always have to edit the DL_DIR
variable during "make menuconfig".

It would be nice to be able to override the ".config" 
value of DL_DIR in the shell environment.

Here is a simple patch which will, 
if you define

$ export BUILDROOT_DL_DIR /usr/local/install/downloads

in your ".bashrc", override the DL_DIR in the ".config".
