This is necessary so that you can build a complete system from scratch in the
right order, i.e:

# export ROOT=/mnt/gentoo
# emerge system

It's just safer to have some of these basic dependencies (like virtual/glibc)
since they help "emerge system" with the build ordering.  Also, some of these
more basic dependencies *may not* be standard for embedded Gentoo Linux systems.
