Looks fine if you remove the commented-out lines and add a clearer comment.

Normally no comma for this case.  The second name should
be lined up under the first name, not just indented by a tab.
(In Emacs, just hitting TAB twice at bol dtrt.)

For .PRECIOUS, say "Add %.symlist pattern to prevent intermediate file
deletion" or something like that.

I'd say:

# The .PRECIOUS rule prevents the files built by an implicit rule whose
# target pattern is %.symlist from being considered "intermediate files"
# and automatically removed.  We only want these files to be removed by
# 'make clean', which is handled by the 'generated' variable.
