config: make it possible to specify which config file to use for 'make defconfig'
So that this works: % make defconfig BR2_DEFCONFIG=~/buildroot-defconfig Right now we have to do: % cp ~/buildroot-defconfig configs/buildroot_defconfig % make buildroot_defconfig That would dirty the buildroot tree and requires it to be writable.
