make linux-libc-dev & linux-libc-dev-cross M-A:foreign Arch:all

1) there was broad agreement in Riga
2) there is partial agreement in Debian too
3) attempt to implement this in noble
4) changes required to:
linux
linux-uapi
cross-toolchain-base-*

5) if things don't work out, fallback plan is to revert linux-libc-dev-cross; or to revert linux-libc-dev changes; or both of them and go back to how things were in mantic.
