I don't think there is any real confusion. The first-order sysdeps/
subdirectory names use the configure tuple vocabulary, so it's i386
because that's the CPU name in the tuple. Indeed using different
names would be a giant pain technically, but I also think it would
create confusion, not reduce it.
