Use set +h and reset umask in stage0
Remove busybox fsck
Also create /dev/pts and /dev/shm
Remove set +h

It is not portable.
Remove unused entries in DEPS
Add tinyxlib and tinyxserver
List dependencies explicitly

This is by far the simplest approach as packages previously
in cross-scripts/ could also depend on other packages.
/include and /lib should point to the correct place
Set up links properly
Don't use pushd/popd in mkinitrd
Update kernel config
Remember to do mkfontscale and mkfontdir
