commit: https://git.buildroot.net/buildroot/commit/?id=45f03959719b4b7c06818a82d9830db7f9d23d96
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
For symmetry with the Kconfig-based packages offering comprehensive
targets like linux-update-defconfig, barebox-update-defconfig and so
on, add a new top level update-defconfig target to run savedefconfig.
