FreeBSD initializes it before using it.

Try defining bcopyw and bcopy as bcopyb in syscons, and using pcvt.
bcopyw is currently defined as bcopy.  Undef'ing it won't work, since
bcopyw() went away.  There are some bcopy's that should probably be
bcopyw's or bcopyb's.  pcvt uses bcopyb in just one place for accessing
character sets.
