The current script can overwrite drivers which are set as built-in in
the board-specific config. This is not desirable.
Add a check to ensure we do not convert built-in stuff into modules.

This was introduced in 6.2 but was removed from the kernel code
in 6.15.
We are currently building cores for sunxi starting from 6.6.
Therefore, a simple replacement without conditions.
- turns out `pahole` for `vmlinux` can take multiple gigabytes of RAM to run successfully
- I can't simply decide based on available RAM, as that would make .config hashes mismatch
- thus, introduce:
- default is to enable BTF; if on low-ram host, error out unless KERNEL_BTF=yes is passed
- if KERNEL_BTF=no is passed, the BTF debug info is always disabled
- if KERNEL_BTF=yes is passed, then a warning is produced, but BTF is still enabled
- the magic number "6451 MiB" was determined empirically (and is probably bs)
- we need to run the hooks _before_ running oldconfig, otherwise it is too late
- drop `kernel_config_check_and_repair()` since it won't ever detect anything now
* Refactor armbian-config into install as external package
- https://github.armbian.com/configng repository is always present
- package can still be removed from the install list
Since this tool will have deeper integration with Armbian, we should probably drop possibility to remove the tool from the list.
* Enable armbian-config as extension
- with DEBUG=yes, allows us to see what is leftover in directory during builds
- with new cleaning in separate commit, there shouldn't be any leftovers _at all_
- with this, every u-boot build will be a full rebuild.
- still, building u-boot is pretty fast
- and it is better to be a bit slower and actually produce correct results
- incl some indicative fdt/extlinux/gpt info
- include full config and defconfig for each target
- mark the old .config file as legacy (it was always the last-target's config)
- fix: savedefconfig after build, not before (as target_map might change it)
- fix: some very old u-boots (2011, odroidc1) do not have `savedefconfig` at all, so make it optional
- fix: same for `.config` -- very old u-boots worked different (`boards.cfg`?)
- this affects `rewrite-kernel-config` and `kernel-config` CLIs
- this does not actually change the .config's we have, that will happen later / gradually as configs are rewritten
- no more `.defconfig` files are produced (they were in gitignore)
