yeah, bootstrap is the most important use case of this, while we can
still have other
cases to use this, such as it can be used to build kernel or something
else no depends
on libc or any other system libraries.
Since here we can get it have correct dependency, and without breaking
the host system,
why not do it correctly?

This is a great package. I noticed it before.
While I plan to bootstrap with another way: write a script to it step
by step instead of
put them in a single package.
Maybe by it, I can get more automation.

1. build dpkg with architecture support patch.
2. build cross binutils
3. build stage1 gcc
4. build linux kernel (to get linux-libc-dev and workable linux-image)
5. build eglibc (maybe by clang? which may be easier to get multilib support)
....

With help of a private repository, this script maybe can work automatic.
