For some unknown reason, having a big "for" loop in the Makefile to scan 

all the "packet-XXX.c" files doesn't work with some "make"s; they seem
to pass only the first few names in the list to the shell, for some
reason.

Therefore, we use a script to generate the "register.c" file, and run
that script from the Makefile.
