where does it generate assembly assembly / llvm ir / machine code? I poked around and didn’t immediately spot this, or even which it targets.

GDSL is written in C++ with use of STL, templates and lambdas, so it's 2600 lines of such C++ source code. There is no self-hosting: neither the LISP compiler nor the C compiler can compile itself. No operating system is implemented, the word kernel in the title means something else.
FYI Here is a 700-line subset-of-C compiler which can compile itself: https://github.com/valdanylchuk/xcc700 . FYI The linker and the libc are not included.

Looks interesting. The next step may be to show some little fun examples built with it.
Here's my similar project from a few years ago, in case you want to compare notes:

I thought you needed 100k lines of code for a C compiler. https://www.anthropic.com/engineering/building-c-compiler
