In that case, from what I understand, cmake will use its bundled copy, so it
is not a good idea to drop the input.

I wondered about this; it is quite probable they behave differently.
But the Makefile calls a test program which I think is bsdtar in this case.

Well, I suppose they have no side effects except for disabling the build
of bsdtar and bsdcpio, and I do not see why we would have a use for them
on guix. Cmake itself links to libarchive as shown by "ldd", so it should
not be affected.
