You appear to have missed:
https://github.com/fosslinux/live-bootstrap
and
https://github.com/ironmeld/builder-hex0
and
https://git.stikonas.eu/andrius/stage0-uefi

we build all the way up from hex0 to modern GCC+Linux+Guile and include
all of the tools needed by a modern Linux Distro.

and you seem to depend upon a POSIX kernel written in C that requires
TCC to compile it.
