[Buildroot] [PATCH 5 of 5 RFC] busybox: update-config: preserve freshly configured settings

[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, All,

> In the sequence:
> 
> make busybox-menuconfig
> make busybox-update-config
> 
> the freshly configured settings from the menuconfig are lost during the
> update-config step. This is because update-config depends on the configure
> step, which starts by copying the config file to the build directory.
> 
> Instead, stop depending on the configure step from update-config, and
> explicitly call the needed commands before actually copying the config file.
> 
> This has the added bonus that 'busybox-update-config' no longer needs the
> toolchain to be available, which makes:
>     make clean busybox-menuconfig busybox-update-config
> much faster and user-friendly.

> This is a corrolary of bug #7154 https://bugs.busybox.net/show_bug.cgi?id=7154
