configure: Rename FILES variable to LINKS

Browse Source 
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.

Improve the comment to clarify what DIRS and LINKS do and why
it's not a good idea to add things to LINKS with wildcarding.

# build tree in object directory in case the source is not in the current directory
# If we're using a separate build tree, set it up now.
# DIRS are directories which we simply mkdir in the build tree;
# LINKS are things to symlink back into the source tree
# (these can be both files and directories).
# Caution: do not add files or directories here using wildcards. This
# will result in problems later if a new file matching the wildcard is
# added to the source tree -- nothing will cause configure to be rerun
# so the build tree will be missing the link back to the new file, and
# tests might fail. Prefer to keep the relevant files in their own
# directory and symlink the directory instead.
