IIRC another way to do this, which was and possibly still is used on ARM, is to compile on the host with -fllvm, saving the LLVM IR output, and then run opt on the target. This requires the target have an LLVM toolchain at the same (or at least IR compatible, but note that they make few if any guarantees about this) version as the host.

Oh dear; I missed the fact that you lack a cross-compiling toolchain.
Things are much easier if you can cross-compile.
Given your situation your approach is probably the best you can do.
I have never done a native bootstrap like this and consequently have no
idea what challenges lay in wait. It sounds like it may be a long road,
however.
Cheers,
