[1/3] configure: Rename FILES variable to LINKS

The FILES variable is used to accumulate a list of things to symlink
from the source tree into the build tree.  These don't have to be
individual files; symlinking an entire directory of data files is
also fine.  Rename it to something less confusing before we add a few
directories to it.
