We don't store the name of the unpacked source directory anywhere as
static data. How do you know what directory vim unpacks as otherwise?
What we do is something like this:

cd $(SRC); tar -xvf `ls -t $(1) | head -n1` > /tmp/unpacked

That unpacks the source directory and spits out the name of the
directory it just unpacked to /tmp/unpacked.

So, if we want to remove any possible source directories before we start
building a package, and we're not going to either unpack the directory
first or store that static data somewhere, how are we going to know what
directory to remove?

One possible solution is to keep that information in the LFS book for
any package that doesn't do the default of pkgname-vers. Tcl and vim
come to mind. And as Chris already commented in another thread, having
that information in the book as an entity could be useful for other
purposes as well. See the current vim instructions.
