I was well aware of the Makefile rules involving loader.rc
when I did the work I did, and I left them the way they were
as a compromise to all of the people who strongly stated that
they had no intention of using the new bootloader.  I suspect
that _very_ few people have custom loader.rc files.  If
someone wants to tackle making it modular, that's fine with me.
