Busybox is built for the target, not on the host.

There already is a host build of vim, however, it's on packages repo.
I didn't want to import all of that to the main repo, but just build
xxd, which neither has the dependencies nor the build-complexity of
vim, but it's mery a single C file which didn't change in 20 years.

Hence yes, maybe it's ok to duplicate the source file to avoid
downloading vim on the host system.
