[Buildroot] Can "make <>_defconfig" rules be restored?

[Rick Foos <rick@synchromeshcomputing.com>]

Hi All,

I would like to use "_defconfig" files to save and restore specific defaults 
for several platforms.

The Makefile at one point supported loading of user defined "_defconfig" 
files. In the current Makefile the noconfig_targets part of "_defconfig" is 
commented out.

Is there a problem with restoring "_defconfig" file loading?

I searched the list archives on defconfig, but could not find any decision 
on this.

The following patch, restores "_defconfig" file loading limited to files at 
a maxdepth of 4.

This allows "_defconfig" files in packages and tools while avoiding the 
_defconfig files in the linux source directories.

The patch also fixes the find syntax, and allows "_defconfig" files to be in 
the same directory as make.

I'd like to propose that this patch be added, or let me know a better way to 
manage multiple default configurations.

Thanks,
Rick Foos
