Subject: Makefile: add savedefconfig target.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4dfdb877f0c0fe6604b47c90e5e21221a0a5d4d2;p=openwrt%2Fstaging%2Fblogic.git

Makefile: add savedefconfig target.

This writes a file called 'defconfig' which contains only the deltas from
the default configuration.  It's suitable for use as an input defconfig file
for later builds.
