I've audited at least the build-tools target portion, and nothing will
break if we don't build it during the build-tools phase, so long as we
don't try to build sysinstall later. Of course, a stripped termcap
file likely should replace the compiled-in entries. Many people have
had good luck getting the stripped version to be extra-tiny. Also,
many of the entries that are compiled in are no longer relevant, and
could be removed (another reason to have them be in a file sysinstall
reads). The days of 1.2MB floppies that motivated this in the first
place are long gone...
