Goodies attached. crossdev is sys-devel/crossdev-0.9.17-r2. Command to start it
was

USE="-*" crossdev -v \
  --binutils \
  --gcc \
  --kernel \
  --libc \
  --ex-gdb \
  --target arm-softfloat-linux-uclibc

That is, no specific versions were given -- everything is the latest "testing"
level.

you need to emerge unifdef first if you want to use linux-headers-2.6.18

crossdev now forces unifdef into depend
