The famous "A Whirlwind Tutorial on Creating Really Teensy ELF Executables for Linux" tutorial has some good answers for you. https://www.muppetlabs.com/~breadbox/software/tiny/teensy.html https://www.muppetlabs.com/~breadbox/software/tiny/teensy.ht... In short: Compilers don't help l, but with a good macro assembler it is quite convenient. Maybe the author used custom tooling but the assembler route is the easiest if you only need this once or a couple of times.

They are as good as it gets when it comes to not choking on unusual binaries. EDIT: Forgot to mention Ghidra.
