Well, someone appears to have done most of the work for you.  From
aclocal.m4 in GNU fileutils:

jm_PERL.m4
Description: Text document

Apart from that you'd need a target for packets_lsend.[ch], which
ought not to be a lot of trouble.

Off course, if the sort of change that would necessitate recreating
these files is pretty rare, then it's probably not worth it.  Would a
patch that adds comments to that effect in Makefile.am etc. be
welcome?
