commit: http://git.buildroot.net/buildroot/commit/?id=e1b1a18ab63ae3ef4eeb7f7cb4406a9cfbb12035
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

savedefconfig allows to create a minimal defconfig file from an
existing configuration. For example :

 make O=/path/to/some/buildroot/build/directory savedefconfig

will generate a minimal 'defconfig' file in the main Buildroot source
directory.
