This patch is a bit bigger than expected since Gentoo being
non-standard in some places.
1. it is installing binaries at /usr/bin instead of /bin.
2. it is using CamelCase names for consolefonts.
3. /etc/rc.conf:unicode=(yes|no) just forbids loadkeys and setfont
"-u" options, but do not disable the actual kernel default_utf8
from vt module.
