It is all about "bootstrap". Bootstrapping a desktop or server OS (open source), should be only done with a shmol set of shmol programs and reaching a "full" desktop/server OS should be done in shmol number of steps.
This is not possible anymore: you need 7483274932847329 huge programs, and 473892473294 steps to reach a "full" desktop/server OS. This is seriously toxic and broken (mainly because of toxic, corporate grade, GNU software steering started 10 years ago).

fasmg provides elf64 and coff bootstraping assembler (aka itself). Here, at least, things are tried the right sane way.

Drive compiles itself (3300 lines total) in 3.26 seconds and produces 124 kloc of assembly output. (Previous numbers were for version with debugging turned on). Drive is written in itself, first version was interpreted (source in Python).

I think it is the same for GCC. You can't compile GCC from the source without having GCC already compiled and running.

I know of one way to avoid the self dependency. That would be to create a listing with the instructions and resultant hex codes for each line. Then use a hex editor to manually create the first binary. xxd can do hex-to-binary, perhaps piped through sed or awk to remove the comments before parsing.

You can use fasm in any one of your OSes to compile versions for all the others. Then transfer the binary file to the target OS

You can also use fasm in Windows to compile binary outputs for Linux, or Unix, or whatever.

fasm exists in ubuntu's repos, however I cannot seem to find in rh and alpne's repos.
that requires me to have a binary in the source repos. that is not advised.
