I did them this way originally under the notion that helper don't _need_ to be part of Git, and so can be built totally separately (and indeed, the ones in contrib/credential are). But the ones in our main Makefile build on libgit.a, and the resulting binaries are reasonably large. We can slim down our total disk footprint by just making them builtins. This reduces the size of: make strip install from 29MB to 24MB on my Debian system. Note that credential-cache can't operate without support for Unix sockets. Currently we just don't build it at all when NO_UNIX_SOCKETS is set. We could continue that with conditionals in the Makefile and our list of builtins. But instead, let's build a dummy implementation that dies with an informative message. That has two advantages: - it's simpler, because the conditional bits are all kept inside the credential-cache source - a user who is expecting it to exist will be told _why_ they can't use it, rather than getting the "credential-cache is not a git command" error which makes it look like the Git install is broken. Note that our dummy implementation does still respond to "-h" in order to appease t0012 (and this may be a little friendlier for users, as well).
